Kavli Affiliate: Igor Moskalenko | First 5 Authors: Chris Karwin, Simona Murgia, Igor Moskalenko, Sean Fillingham, Anne-Katherine Burns | Summary: An excess $gamma$-ray signal toward the outer halo of M31 has recently been reported. Although other explanations are plausible, the possibility that it arises from dark matter (DM) is valid. In this work we interpret […]

Kavli Affiliate: Eli S. Rykoff | First 5 Authors: LSST Dark Energy Science Collaboration, Bela Abolfathi, David Alonso, Robert Armstrong, Éric Aubourg | Summary: We describe the simulated sky survey underlying the second data challenge (DC2) carried out in preparation for analysis of the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) […]

Kavli Affiliate: R. Morris | First 5 Authors: Jesus M. Salas, Smadar Naoz, Mark R. Morris, , | Summary: The gas dynamics in the inner few kiloparsecs of barred galaxies often results in configurations that give rise to nuclear gas rings. However, the generic dynamical description of the formation of galactic nuclear rings does not […]
Kavli Affiliate: Giorgio Gratta | First 5 Authors: Giorgio Gratta, David E. Kaplan, Surjeet Rajendran, , | Summary: A new technique to search for new scalar and tensor interactions at the sub-micrometer scale is presented. The technique relies on small shifts of nuclear gamma lines produced by the coupling between matter and the nuclei in […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Karime Maamari, Vera Gluscevic, Kimberly K. Boddy, Ethan O. Nadler, Risa H. Wechsler | Summary: We use the latest measurements of the Milky Way satellite population from the Dark Energy Survey and Pan-STARRS1 to infer the most stringent astrophysical bound to date on velocity-dependent interactions between […]
Kavli Affiliate: Igor V. Moskalenko | First 5 Authors: Mikhail A. Malkov, Igor V. Moskalenko, , , | Summary: A recently observed bump in the cosmic ray (CR) spectrum from 0.3–30 TV is likely caused by a stellar bow shock that reaccelerates emph{preexisting} CRs, which further propagate to the Sun along the magnetic field lines. […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: Pavan R. Hebbar, Craig O. Heinke, D. Kandel, Roger W. Romani, | Summary: Redback millisecond pulsars (MSPs) typically show pronounced orbital variability in their X-ray emission due to our changing view of the intrabinary shock (IBS) between the pulsar wind and stellar wind from the companion.
