Evidence for a spectral steepening of the gamma-ray emission from the Galactic Center ridge
A. Acharyya, F. Aharonian, H. Ashkar +130
Very-high-energy (VHE) -ray emission detected from the central molecular zone (CMZ) hints at diffusive propagation of cosmic rays (CRs) injected continuously near the Galactic c…
Sensitivity of the Cherenkov Telescope Array to spectral signatures of hadronic PeVatrons with application to Galactic Supernova Remnants
The Cherenkov Telescope Array Consortium, F. Acero, A. Acharyya +356
The local Cosmic Ray (CR) energy spectrum exhibits a spectral softening at energies around 3~PeV. Sources which are capable of accelerating hadrons to such energies are called hadr…
Figuring Out Gas & Galaxies In Enzo (FOGGIE) VI: The Circumgalactic Medium of Galaxies is Supported in an Emergent, Non-Hydrostatic Equilibrium
Cassandra Lochhaas, Jason Tumlinson, Molly S. Peeples +9
The circumgalactic medium (CGM) is often assumed to exist in or near hydrostatic equilibrium with the regulation of accretion and the effects of feedback treated as perturbations t…
Metallicity, ionization parameter, and pressure variations of HII regions in the TYPHOON spiral galaxies
K. Grasha, Q. H. Chen, A. J. Battisti +12
We present a spatially-resolved HII region study of the gas-phase metallicity, ionization parameter, and ISM pressure maps of 6 local star-forming and face-on spiral galaxies from…
KODIAQ-Z: Metals and Baryons in the Cool Intergalactic and Circumgalactic Gas at 2.2<z<3.6
Nicolas Lehner, Claire Kopenhafer, John O'Meara +8
We present the KODIAQ-Z survey aimed to characterize the cool, photoionized gas at 2.2<z<3.6 in 202 HI-selected absorbers with 14.6<log N(HI)<20, i.e., the gaseous interface betwee…
The physics of gas phase metallicity gradients in galaxies
Piyush Sharda, Mark R. Krumholz, Emily Wisnioski +3
We present a new model for the evolution of gas phase metallicity gradients in galaxies from first principles. We show that metallicity gradients depend on four ratios that collect…
