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…
Accurate Extragalactic Magnetic Fields from Faraday Rotation with Optimal Dispersion Measure Estimators
Hilay Shah, Mark Krumholz, Naomi McClure-Griffiths +1
Faraday rotation measures (RMs) are one of our few observational tools for measuring magnetic field strengths in extragalactic systems, but converting an RM to a magnetic field est…
Multi-wavelength probes of the Milky Way's Cold Interstellar Medium: Radio HI and Optical KI Absorption with GASKAP and GALAH
Hiep Nguyen, Sven Buder, Juan D. Soler +19
We present a comparative analysis of interstellar hydrogen (HI) and potassium (KI) absorption from the radio and optical surveys, GASKAP and GALAH, to study the physical and kinema…
Understanding gas mixing in the circumgalactic medium
Hilay Shah, Freeke van de Voort, Amit Seta +1
We study gas mixing in a simulated Milky Way-mass galaxy's circumgalactic medium (CGM) using cosmological `zoom-in' simulations. We insert tracer dyes in the CGM with different gas…
Wind of Change: Faraday Rotation in a Simulated Large Magellanic Cloud
Hilay Shah, Mark Krumholz, Naomi McClure-Griffiths
Magnetic fields significantly influence the structure of galaxies' interstellar media, but our understanding of magnetic field strengths and structures in external galaxies is seve…
Where has all the -process gone? Timescales for GRB-Kilonovae to Enrich their Host Galaxies
Anya E. Nugent, Alexander P. Ji, Wen-fai Fong +2
Neutron star (NS) mergers are currently the only observed source of -process production in the Universe. Yet, it is unclear how much -process mass from these mergers is incor…
