Summary: This study maps the distribution of galaxies across the Southern Galactic plane using the VISTA Variables in the Via Lactea Survey (VVV), resulting in a catalogue of 5563 visually confirmed galaxies, with 99% being new discoveries. The galaxy density distribution closely resembles the distribution of low interstellar extinction, and the main limitations for detecting background galaxies in the Zone of Avoidance are interstellar extinction and stellar density.

Summary: The goal of this study is to search for AGNs in the Galactic disc at low latitudes. Through analyzing the near-IR and mid-IR properties and variability of five sources, we identified four AGN candidates and one YSO candidate. The results are consistent with previous findings on AGN and quasar variability.

Summary: We present the VST ATLAS Quasar Survey, which includes over 1,229,000 quasar (QSO) candidates with 16 < g < 22.5 over an area of approximately 4,700 square degrees. The survey aims to reach a QSO sky density of 130 deg-2 for z < 2.2 and about 30 deg-2 for z > 2.2. The selection of candidates is guided by X-ray/UV/optical/MIR data in the William Herschel Deep Field (WHDF) and we find that about 25% of the QSOs are morphologically classified as optically extended. In terms of completeness and contamination, MIR, UV, and X-ray selections are 70-90% complete, with X-ray suffering less contamination than MIR and UV.

Summary: The WALLABY pilot data release 1 is the first public release of H I pilot survey data from the Wide-field ASKAP L-band Legacy All-sky Blind Survey. It covers three 60 deg(2) regions on the sky targeting nearby galaxy clusters and groups, with a relatively low median redshift. The survey has uncovered technical issues and artefacts that are expected to be addressed before the full WALLABY survey.

Summary: We present a revised measurement of the extragalactic background light (EBL) at radio frequencies based on a near complete compendium of radio source counts. We report the radio-EBL at multiple frequencies, each showing a two-humped distribution that matches well with active galactic nucleus (AGN) and star-forming galaxy (SFG) populations, with both populations contributing roughly equal energy.

Summary: This study presents uniformly reprocessed and re-calibrated data from the RoboPol programme of optopolarimetric monitoring of active galactic nuclei (AGNs) between 2013 and 2017, covering a total of 5068 observations of 222 AGNs with Dec. > -25(circle). The current version of the RoboPol pipeline used to process and calibrate the entire data set is described, with average quantities summarizing optopolarimetric behaviour provided for each source observed and for the time interval followed.

Summary: This study examines the relationship between HI-to-stellar mass ratio and star formation properties probed by optical emission lines, finding a weak correlation at short time scales but a stronger connection at longer time scales. The research also identifies a correlation between oxygen equivalent width and gas-phase metallicity, and suggests that gas-rich galaxies may have higher fractions of diffuse and/or shock-heated gas.

Summary: In this study, we investigated the properties of the faint radio source population detected in the COSMOS field using the MeerKAT International GHz Tiered Extragalactic Exploration (MIGHTEE) Early Science data, with a focus on the radio-loud active galactic nuclei (AGNs). Based on extensive multiwavelength data, we classified 88% of the 5223 radio sources in the field as AGNs or star-forming galaxies. We selected a sample of radio-loud AGNs with redshifts up to z~6 and studied their classification as high-excitation and low-excitation radio galaxies (HERGs and LERGs).

Summary: The North Ecliptic Pole field is a popular location for satellite observations, and recent research using the Hyper Suprime-Cam has identified new sources and gathered multi-band photometry data. This new band-merged catalogue will be valuable for current and future space missions planning deep observations in the NEP field.

The catalogue in SDSS Data Release 16 includes 2740 visually inspected galaxy clusters with a median of approximately 10 members per cluster. Through obtaining five redshifts below z < 0.3, over 99% of clusters can be validated.

Summary: This study reveals the bimodality in various properties of galaxy populations. Using the Self-Organizing Maps (SOM) technique, the clustering results in the feature space can be mapped onto a 2D representation. The analysis indicates the existence of three or five sub-populations. Moreover, multiple interstitial populations within the "green valley" galaxies are identified. The study also shows the capability of SOMs in separating certain morphological features.

Summary: We analyze the spectra of host galaxies from the Dark Energy Survey to investigate the correlations between Hubble diagram residuals and spectral properties. We find weak correlations between Hubble residuals and the strengths of certain emission lines. However, the well-known correlation between Hubble residuals and host galaxy stellar mass is stronger. These findings suggest that dust plays a role in the measurement of cosmological parameters.

Summary: This research presents two new approaches to aid in the production of future hard X-ray catalogues, reducing the reliance on human intervention during the detection of faint excesses in maps that contain systematic noise. A convolutional neural network has been trained to create a more sensitive source detection tool, while a method based on Bayesian reasoning is better able to combine detections from multiple observations. These improved techniques detect previously undetected sources in the data set used to derive the published catalogue.

Summary: LiteBIRD is a space mission that aims to explore the origins of the universe and fundamental physics. It will be launched by JAXA in the late 2020s and will orbit the Sun-Earth Lagrange point L2.

Summary: To ensure the accuracy of cosmic microwave background (CMB) polarization measurements, it is crucial to control systematic errors. This study uses a ray-tracing-based modeling technique to predict the far sidelobes of a CMB telescope in the South Pole and proposes a highly scattering surface to reduce the contrast of far-sidelobes.

Summary: This paper investigates the use of cosmic microwave background (CMB) polarization data to confirm anomalies in CMB temperature data. It finds that the E-mode estimators provide a largely independent check on these anomalies, with correlation coefficients between temperature and E-mode estimators less than 0.1. The study also shows that future experiments like the LiteBIRD survey can significantly reduce errors in anomaly estimators, particularly for the lack of large-scale correlation. The improvement in other anomalies like Q-O alignment is less clear due to cosmic variance.

Summary: We measured the polarization fraction of 6282 Galactic cold clumps at 353 GHz, finding a mean-squared polarization fraction of (4.79 +/- 0.44) x 10(-4). We tested various physical properties of the clumps and found a trend of increasing polarization fraction with increasing Galactic latitude. The Simons Observatory is expected to greatly enhance our ability to study the magnetic field structure in Galactic cold clumps.

Summary: We present measurements of the disk-averaged absolute brightness temperatures of Venus at four microwave frequency bands. The temperatures measured were 432.3 +/- 2.8, 355.6 +/- 1.3, 317.9 +/- 1.7, and 294.7 +/- 1.9 K for frequency bands centered at 38.8, 93.7, 147.9, and 217.5 GHz, respectively. Our analysis suggests higher mean atmospheric temperatures and lower abundances of microwave continuum absorbers compared to prior radio occultation measurements.

Summary: The power spectrum of cosmic microwave background (CMB) lensing provides valuable information for understanding fundamental physics, such as neutrino masses and dark energy. Current lensing measurements focus on temperature distortions, but future experiments with greater sensitivity will be dominated by polarization lensing signals. Anisotropic birefringence, which refers to the rotation of linear polarization direction of CMB photons, can bias the measured lensing power spectrum, and measurement of this effect is important for future low-noise polarization experiments.
