Astronomical Advantages of a Boost Mission to Facilitate HST Science into the 2030s: Imaging the Circumgalactic Medium of Galaxies
Matthew J. Hayes, Kate H. R. Rubin, Michelle A. Berg +20
We present the case for imaging ultraviolet line emission from highly ionized metals and HI Lya in the circumgalactic medium of galaxies, should the Hubble Space Telescope receive…
Age and metallicity of low-mass galaxies: from their centres to their stellar halos
Elisa A. Tau, Antonela Monachesi, Facundo A. Gómez +5
We aim to analyse the metallicity and the ages of the stellar halos of low-mass galaxies to better understand their formation history. We use 17 simulated low-mass galaxies from th…
Coupling between stellar and HI lopsidedness in Milky Way-type galaxies from the Auriga Superstars cosmological simulations
Arianna Dolfi, Facundo A. Gómez, Rebekka Bieri +5
Lopsidedness is common in disk galaxies, yet its origin and evolution remain unclear. Previous studies typically examined stellar and gas asymmetries separately, but a combined ana…
Revisiting radio synchrotron diagnostics in star-forming galaxies
Maria Werhahn, Christoph Pfrommer, Philipp Girichidis +7
Radio continuum observations are widely used to study cosmic ray (CR) electron populations and transport processes in star-forming galaxies, but their interpretation relies on seve…
FEASTS and MHONGOOSE: HI Column Density Distribution at for
Jing Wang, Xuchen Lin, Ze-Zhong Liang +24
We present the first HI column density distribution function, , extending down to . This was derived from high-s…
Stirring Things Up: Bar-induced substructures in the stellar halo of a cosmological Milky Way analogue
Thomas Tomlinson, Francesca Fragkoudi, Andreia Carrillo +8
The stellar halo of the Milky Way contains the remnants of past accretion events, which could be detectable as substructures in the classical integrals of motion space, such as ene…
