On the Existence of the Plateau Emission in High-Energy Gamma-Ray Burst LightCurves observed byFermi-LAT

Kavli Affiliate: Nicola Omodei | First 5 Authors: Maria Giovanna Dainotti, Nicola Omodei, Gokul . P. Srinivasaragavan, Giacomo Vianello, Richard Willingale | Summary: The Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope (Fermi) shows long-lasting high-energy emission in many gamma-ray bursts (GRBs), similar to X-ray afterglows observed by the Neil Gehrels Swift […]

The Atacama Cosmology Telescope: Microwave Intensity and Polarization Maps of the Galactic Center

Kavli Affiliate: Susan E. Clark | First 5 Authors: Yilun Guan, Susan E. Clark, Brandon S. Hensley, Patricio A. Gallardo, Sigurd Naess | Summary: We present arcminute-resolution intensity and polarization maps of the Galactic center made with the Atacama Cosmology Telescope (ACT). The maps cover a 32 deg$^2$ field at 98, 150, and 224 GHz […]

On the origin of observed cosmic ray spectrum below 100 TV

Kavli Affiliate: Igor V. Moskalenko | First 5 Authors: Mikhail A. Malkov, Igor V. Moskalenko, , , | Summary: Significant progress in cosmic ray (CR) studies was achieved over the past decade. Particularly important are precise measurements of primary and secondary species in the TV rigidity domain that show a bump in the spectra of […]

Signatures of Recent Cosmic-Ray Acceleration in the High-Latitude $γ$-Ray Sky

Kavli Affiliate: Troy A. Porter | First 5 Authors: Guðlaugur Jóhannesson, Troy A. Porter, , , | Summary: Cosmic-ray (CR) sources temporarily enhance the relativistic particle density in their vicinity over the background distribution accumulated from the Galaxy-wide past injection activity and propagation. If individual sources are close enough to the solar system, their localised […]

Cosmological Evolution of the Formation Rate of Short Gamma-ray Bursts With and Without Extended Emission

Kavli Affiliate: Vahe Petrosian | First 5 Authors: Maria Giovanna Dainotti, Vahe’ Petrosian, Luke Bowden, , | Summary: Originating from neutron star-neutron star (NS-NS) or neutron star-black hole (NS-BH) mergers, short gamma-ray bursts (SGRBs) are the first electromagnetic emitters associated with gravitational waves. This association makes the determination of SGRB formation rate (FR) a critical […]

Projected sensitivity of the LUX-ZEPLIN (LZ) experiment to the two-neutrino and neutrinoless double beta decays of $^{134}$Xe

Kavli Affiliate: T. A. Shutt | First 5 Authors: The LUX-ZEPLIN, Collaboration, :, D. S. Akerib, A. K. Al Musalhi | Summary: The projected sensitivity of the LUX-ZEPLIN (LZ) experiment to two-neutrino and neutrinoless double beta decay of $^{134}$Xe is presented. LZ is a 10-tonne xenon time projection chamber optimized for the detection of dark […]

Neutral vs Ion Linewidths in Barnard 5: Evidence for Penetration by MHD Waves

Kavli Affiliate: Sarah E. Church | First 5 Authors: Jaime E. Pineda, Anika Schmiedeke, Paola Caselli, Steven W. Stahler, David T. Frayer | Summary: Dense cores are the final place where turbulence is dissipated. It has been proposed from theoretical arguments that the non-thermal velocity dispersion should be narrower both for molecular ions (compared to […]

Composition of Terrestrial Exoplanet Atmospheres from Meteorite Outgassing Experiments

Kavli Affiliate: Laura Schaefer | First 5 Authors: Maggie A. Thompson, Myriam Telus, Laura Schaefer, Jonathan J. Fortney, Toyanath Joshi | Summary: Terrestrial exoplanets likely form initial atmospheres through outgassing during and after accretion, although there is currently no first-principles understanding of how to connect a planet’s bulk composition to its early atmospheric properties. Important […]

Cosmological Evolution of Fermi-LAT Gamma-ray Blazars Using Novel Nonparametric Methods

Kavli Affiliate: Vahe Petrosian | First 5 Authors: Houdun Zeng, Vahé Petrosian, Tingfeng Yi, , | Summary: Multi-wavelength analyses of spectra of active galactic nuclei (AGNs) provide useful information on the physical processes in the accretion disk and jets of black holes. This, however, is limited to bright sources and may not represent the population […]
