Spirited Away: Advective Loss of Cosmic Rays into the Milky Way's Circumgalactic Medium Explains the Large Magellanic Cloud's Low Gamma-ray Luminosity
Taaseen Islam, Hilay Shah, Mark R. Krumholz +1
Models of galactic-scale cosmic ray production and transport have successfully reproduced the radio and -ray spectra of many galaxies; however, one notable exception is the Lar…
LMC-induced Perturbations in the Milky Way Halo II: Bridging Field-level Inference and Summary-level Simulation-Based Inference
Yanjun Sheng, Yuan-Sen Ting, Tomasz RóżaÅski +3
The gravitational interaction between the Milky Way (MW) and the Large Magellanic Cloud (LMC) drives the outer halo into dynamical disequilibrium, imprinting the masses and structu…
SKAO and Gamma-Ray Synergies
Gianluca Castignani, Gavin Rowell, Arnau Aguasca-Cabot +26
A wide variety of Galactic and extragalactic sources are known to emitradiation across the entire electromagnetic spectrum, including both transient and steady-state phenomena. A f…
Analysis and implications of the spatio-spectral morphology of the Fermi Bubbles
Ami Tank, Roland Crocker, Mark R. Krumholz
The Fermi Bubbles are gamma-ray structures extending from the center of the Milky Way to +/-50 degree Galactic latitude that were discovered in data obtained by the Fermi/LAT instr…
Not Where You Left Them: Displaced -Rays and X-Rays Reveal the Cosmic Ray Scattering Rate
Manami Roy, Mark R. Krumholz, Roland M. Crocker +1
Modern X-ray and -ray instruments are revealing a growing class of Galactic non-thermal sources whose emission centroids are measurably offset from the nearest plausible sites…
Updated Constraints on the Injection Energy of Positrons Generating the Galactic 511 keV -ray line
Souradeep Das, Mark R. Krumholz, Roland M. Crocker +2
Even 50 years after the discovery of a positron annihilation line from the inner Galaxy, no class of astrophysical sources has emerged as a definitive explanation for both the emis…
