Abstract

Ground-based gamma-ray astronomy has witnessed a major breakthrough with the results of the current generation of imaging atmospheric Cherenkov telescopes. In order to exploit the full physics potential of this field, the next generation instrument-the Cherenkov Telescope Array CTA-aims for an improvement in sensitivity by an order of magnitude with respect to current experiments, an extension of the accessible energy regime from some tens of GeV into the 100 TeV range and improved angular and energy resolution. CTA will therefore need to consist of similar to 50-100 telescopes. The development and application of cost effective technologies with significantly improved reliability and maintainability may be a major challenge. To optimize the design, the CTA consortium is performing a dedicated design study. (C) 2010 Elsevier B.V. All rights reserved.

New bound on Lorentz violation based on the absence of vacuum Cherenkov radiation in ultrahigh energy air showers

Fabian Duenkel, Marcus Niechciol, Markus Risse

Summary: In this study, the effects of isotropic, nonbirefringent Lorentz violation in the photon sector on extensive air showers induced by ultrahigh energy cosmic rays are investigated. Simulating air showers, a significant reduction in the calculated average atmospheric depth of the shower maximum (Xmax) is observed when this Lorentz-violating effect is implemented. A new bound on Lorentz violation is derived by considering (Xmax) and its shower-to-shower fluctuations sigma(Xmax), improving the previous bound by a factor of 2. This is the first bound based on the absence of vacuum Cherenkov radiation from fundamental particles (electrons and positrons) in air showers. Options for further improvements are discussed.

Telescope array bursts, radio pulses and axion quark nuggets

Xunyu Liang, Ariel Zhitnitsky

Summary: The Telescope Array experiment has recorded several short time bursts of air shower events that are strongly correlated with lightning, possibly representing the direct manifestation of dark matter annihilation events within the axion quark nugget model. This study suggests testing this proposal by searching for radio signals within a specific frequency range, which can be easily discriminated from conventional lightning-induced radio emission.

Summary: KM2A, a sub-array of LHAASO, is designed to observe a large fraction of the northern sky for gamma-ray sources above 10 TeV. This paper presents the data analysis pipeline and first observation of the Crab Nebula by KM2A, detecting gamma-ray signals with high significance. The energy spectrum of the Crab Nebula in the range 10-250 TeV is consistent with previous measurements, indicating the potential discovery of new ultrahigh-energy gamma-ray phenomena.

Summary: The Earth is bombarded by ultrarelativistic particles known as cosmic rays, believed to have a Galactic origin. The HAWC observatory discovered a gamma-ray source, HAWC J1825-134, extending beyond 200 TeV, coincident with a giant molecular cloud with a high gas density of 700 protons/cm(-3). It is likely that cosmic rays accelerated to energies of several PeV colliding with the ambient gas produce the observed radiation.

Summary: The Laser Interferometer Gravitational-wave Observatory and Virgo Collaboration detected the gravitational wave event S200224ca from a binary black hole merger during their third observing run in February 24, 2020. Follow-up observations by the Neil Gehrels Swift Observatory covered a significant portion of the error region, making S200224ca the most thoroughly followed-up binary black hole event in near-UV and X-ray to date. However, no likely electromagnetic counterparts to the event were found in the searches conducted by Swift and other observatories.

Summary: This study aims to provide a firm detection of the oxygen-rich SNR LMC N132D in the VHE gamma-ray domain and clarify its spectral characteristics and emission localization. The analysis of an extended data set and Fermi-LAT data reveals a high luminosity of N132D at GeV and TeV energies, along with a lower limit on a gamma-ray cutoff energy of 8 TeV with a 95% confidence level. The new gamma-ray spectrum and multiwavelength observations suggest a hadronic origin of the VHE gamma-ray emission from N132D.

Summary: Magnetar hyperflares are the most likely explanation for fast radio bursts. The first observational evidence supporting this scenario was obtained in April 2020, when an FRB was detected from the Galactic magnetar SGR 1935+2154. Follow-up observations by H.E.S.S. provided high-energy gamma-ray observations of a magnetar in a flaring state.

Reduction of light output of plastic scintillator tiles during irradiation at cold temperatures and in low-oxygen environments

B. Kronheim, A. Belloni, T. K. Edberg, S. C. Eno, C. Howe, C. Palmer, C. Papageorgakis, M. Paranjpe, S. Sriram

Summary: This paper presents measurements of the relative decrease of light output during irradiation of small plastic scintillator tiles read out by silicon photomultipliers. The study found substantial temporary damage during low-temperature irradiation, regardless of oxygen concentration and wrapping material. The wrapping material had an impact on the relative light loss, with the 3M(TM) Enhanced Specular Reflector Film showing the largest loss. The light loss was less at warmer temperatures and similar to that in standard atmosphere with 3% oxygen concentration. Evidence of a plateau in the radical density was seen for the data at 0 degrees C.
