Galactic coronae in Milky Way-like galaxies: the role of stellar feedback in gas accretion

F Barbani, R Pascale, F Marinacci… - Monthly Notices of …, 2023 - academic.oup.com
Star-forming galaxies like the Milky Way are surrounded by a hot gaseous halo at the virial
temperature–the so-called galactic corona–that plays a fundamental role in their evolution …

Using 44Ti emission to differentiate between thermonuclear supernova progenitors

D Kosakowski, MI Ugalino, R Fisher… - Monthly Notices of …, 2023 - academic.oup.com
The radioisotope 44Ti is produced through α-rich freezeout and explosive helium burning in
