Summary: In this study, two galaxy models (Illustris'ING and SC-SAM) were compared for their predictions on large scale structure observables for stellar mass selected samples at z=0. The models show good agreement in two-point clustering and galaxy assembly bias, but differences in areas such as halo gas content correlation with environment and occupancy predictions for low-mass haloes. Higher order statistics help accurately describe the galaxy distribution and differentiate between models showing similar behavior in two-point statistics. SAMs are suggested as a promising method for generating mock catalogues for future cosmological surveys.

Summary: The study investigates the jackknife method for internal covariance estimation in large-scale structure surveys, exploring the impact of jackknife size and number of resamplings on the precision of the covariance estimate and errors in cosmological parameters. Results show that the baryon acoustic scale error estimate is independent of the jackknife scale, while the shift parameter a exhibits variations in error estimates from different datasets.

Summary: Modern redshift surveys are mapping the distribution of galaxies on enormous distance scales. However, current hydrodynamical simulations cannot reach the volumes needed for upcoming surveys. A new, large volume hydrodynamical simulation called MillenniumTNG (MTNG) is able to accurately reproduce the observed clustering of galaxies, but there are discrepancies when separated by color. This is due to the quenching of satellite galaxies in the model.

Summary: The study indicates that star formation in galaxies and AGN jets have significant impacts on the distribution of matter, especially causing baryon evacuation at different redshifts. In larger systems, AGN jets are particularly efficient in evacuating baryons, leading to the majority of baryonic mass being in the IGM.

Summary: Research has shown that galaxies in cosmic voids exhibit delayed evolution compared to the rest of the Universe, indicating interactions between galaxies and their environment. The extent to which large-scale structures influence the properties of void galaxies, or if they are primarily influenced by the low local density typical of these regions, remains unclear. In this study, cosmic voids were identified in SDSS-DR16, and the g-r colour, star formation rate, and concentration of galaxies were examined. Results showed that galaxies in voids had bluer colours, higher star formation rates, and lower concentrations, particularly for haloes of a certain mass. Additionally, the properties of galaxies were found to be sensitive to the type of void they inhabited, suggesting a correlation between galaxy properties and the large-scale environment provided by voids.

Summary: In this study, a model is developed using conditional matching and Markov Chain Monte Carlo method to interpret the small-scale clustering of eBOSS galaxies from Sloan Digital Sky Survey IV. It is found that by matching the star formation rate of galaxies and the halo accretion rate, the eBOSS ELG small-scale clustering can be reproduced within 1 sigma error level.

Summary: The co-evolution between central supermassive black holes, their host galaxies, and dark matter haloes is still a matter of intense debate. Recent work shows that AGN clustering can be a powerful tool in breaking degeneracies and diagnosing the BH-galaxy connection. Current data suggest relatively high values of AGN in satellites, indicating disc instabilities play a significant role in triggering AGN. Future surveys like Euclid/LSST will be crucial in shedding light on the BH-galaxy co-evolution.

Summary: The clustering of galaxy groups in the GAMA survey shows a strong dependence of group profile on separation scale and group mass, with the most massive groups residing in extended, overdense structures. Marked clustering statistics reveal peaks on scales comparable to typical group radius, showing no indication of galaxy mass segregation within groups. Results from simulations suggest L-GALAXIES model exhibits enhanced bias and galaxy mass dependence on small scales.

Summary: The planar distributions of satellite galaxies around the Milky Way and Andromeda have been extensively studied, and now this study is extended to the satellite galaxies of massive galaxy clusters. The results show that both observations and simulations of galaxy clusters indicate an excess of anisotropic satellite distributions. The normal vector of the satellite plane is strongly aligned with the host halo's minor axis, while the alignment with the large-scale structure is weak. The degree of anisotropy is higher at higher redshift and satellite galaxies are mostly accreted singly, suggesting that group accretion is not responsible for the high flattening of satellite planes.

Summary: The study finds that the stellar mass-size relations of central and satellite galaxies are similar, but their halo mass-size relations differ significantly. Larger halo masses tend to host larger central galaxies, while the size of satellite galaxies is only slightly dependent on halo virial mass. The results are consistent with a model where the size of galaxies scales with the cubic root of their host halo mass, with satellites being slightly smaller than central galaxies, likely due to tidal stripping.

Summary: This study discusses the interest in ultralight bosonic particles of mass around 10(-22) eV/c(2) as a dark matter candidate, highlighting their potential impact on small-scale tensions in the standard cosmological model. By simulating fuzzy dark matter (FDM) dynamics with non-linear wave effects, the study reveals the suppression of power on small scales relative to cold dark matter (CDM) and the computational challenges associated with FDM equations. The simulations provide insights into the evolution of matter power spectrum and the halo mass function of FDM.

Summary: The study investigates the dependence of galaxy clustering amplitude on star formation rate and stellar mass at 0.7 < z < 1.5 redshift. It reveals a strong correlation between clustering amplitude and H alpha luminosity, but this dependence is eliminated at fixed stellar mass. Satellite galaxies contribute to the small residual correlation observed at fixed stellar mass.

Summary: We evaluate the consistency between lensing and clustering by combining measurements from Baryon Oscillation Spectroscopic Survey, DES Year 3, HSC Year 1, and KiDS-1000. Good agreement is found between these lensing data sets. Two fixed cosmologies, Planck and Lensing cosmology, are used to fit the data, and both provide an acceptable fit at large scales. However, uncertainties in baryon feedback and assembly bias hinder the full utilization of small-scale measurements.

Summary: We propose a technique for estimating the mass of dark matter halos in local galaxies based on photometric measurements, allowing us to establish the relationship between stellar mass and halo mass down to stellar masses of 10^(5) M. We find no significant differences among the relationships in four local galaxy clusters or between the clusters and field galaxies, and our results agree with previous studies using abundance matching methods. By fitting a power law to our empirical relationship, we determine that for stellar masses less than 10^(9) M, the halo mass is M_h = 10^(10.35 +/- 0.02)(M_* / 10^(8) M)(0.63 +/- 0.02). However, this relationship is susceptible to systematic modeling errors and the uncertainties quoted refer to the uncertainties in the median relationship. The scatter about the fit in halo mass, including uncertainties from our methodology, is 0.3 dex for galaxies that meet our selection criteria and have stellar masses less than 10^(9) M. Additionally, we apply the same technique to lower luminosity galaxies in the Local Group and find evidence for additional mass beyond the effective radius that is not accounted for by the standard dark matter profile. If this mass is in the form of a central black hole, their masses are in the range of intermediate mass black holes, around 10^((5.7 +/- 0.6)) M, corresponding to a few percent of the halo mass and higher than extrapolated values for more massive galaxies.

Summary: We developed a pipeline called mentari to generate the spectral energy distribution (SED) of galaxies across a wide wavelength range using the Dusty SAGE model. By incorporating dust-related processes, our physically motivated attenuation model provides a more consistent description of galaxy formation and evolution than a constant attenuation. Our predictions agree reasonably well with observations in terms of the luminosity functions and cosmic SED, although our model underproduces far-ultraviolet emission at higher redshifts, indicating the need for further improvements in AGN feedback and dust processes.

Summary: This paper utilizes a fully numerical model to study the small-scale clustering of galaxies, aiming to provide robust constraints on the galaxy-halo connection and test the Planck ?CDM cosmology. The study explores two extensions to the standard Halo Occupation Distribution model: assembly bias and velocity bias. The results show that for low-luminosity galaxies, a model considering both assembly bias and velocity bias fits the clustering measurements well, while for high-luminosity galaxies, the model exhibits significant tension with SDSS measurements.

Summary: We analyze clustering measurements of BOSS galaxies and use a simulation-based emulator of two-point statistics. Our results show lower scaling parameters compared to Planck observations, suggesting a possible unknown systematic error in the galaxy bias model at nonlinear scales. However, we note that the BOSS data is well fit assuming general relativity (GR) and further data and modeling will enhance our understanding of the galaxy-halo connection.

Summary: The PRObabilistic Value-added Bright Galaxy Survey (PROVABGS) catalog will provide measurements of galaxy properties for over 10 million galaxies of the Dark Energy Spectroscopic Instrument (DESI) Bright Galaxy Survey. This is achieved through Bayesian spectral energy distribution (SED) modeling of DESI spectroscopy and Legacy Surveys photometry. The study accurately infers the galaxy properties and demonstrates the importance of a joint analysis of spectra and photometry in improving constraints on galaxy properties.

Summary: We conducted an investigation into the first 500 million years of galaxy evolution using the CEERS survey. By analyzing the CEERS NIRCam imaging data, we identified a sample of 26 galaxy candidates at z similar to 9-16, suggesting that the number density of galaxies at this redshift range remains relatively constant. These findings highlight the potential of JWST to discover more ultrahigh-redshift galaxies in the future.

Summary: Mid-infrared (mid-IR) observations are used to identify heavily obscured active galactic nuclei (AGN) that are difficult to detect in other wavelengths. The Mid-Infrared Instrument (MIRI) on the James Webb Space Telescope provides data for such studies. Utilizing MIRI imaging data, researchers investigated the AGN population in the distant universe and classified them into different types based on their spectral energy distribution (SED). The study shows that MIRI can identify a large population of heavily obscured AGN missed by X-ray surveys at high redshifts.

Summary: We conducted a joint analysis of galaxy two- and three-point correlation functions to test modified gravity theories and constrain non-linear effects on cosmological scales. Applying this analysis to BOSS data, we obtained lower bounds on the parameters characterizing the time evolution of the second-order velocity field, which are consistent with GR predictions. The results showed significant improvement compared to the analysis using only the isotropic three-point correlation function.

Summary: In this study, the quiescent lives of central galaxies were explored using the Semi-Analytical Galaxy Evolution galaxy model and Uchuu dark matter simulation. The study focused on three questions: the percentage of a galaxy's life spent in quiescence, the frequency of galaxies transitioning off the main sequence, and the typical duration of a quiescent phase. The findings showed that low- and high-mass galaxies spend the highest percentage of their lives in quiescence, while low-mass galaxies have more frequent but shorter quiescent periods compared to high-mass galaxies.

Summary: For the first time, we have conducted an observational test of the consistency relation for the large-scale structure (LSS) of the Universe by jointly analyzing the anisotropic two-and three-point correlation functions (2PCF and 3PCF) of galaxies. Using the Baryon Oscillation Spectroscopic Survey (BOSS) Data Release 12, we found no violation of the LSS consistency relation in our analysis within the statistical errors. Our analysis opens up a new observational window to test fundamental physics using anisotropic higher-order correlation functions of galaxy clustering.
