A γ-Ray-emitting Collisional Ring Galaxy System in Our Galactic Neighborhood
The Astrophysical Journal LettersThe astrophysical γ -ray photons carry the signatures of the violent phenomena happening on various astronomical scales in our Universe. This includes supernova remnants, pulsars, and pulsar wind nebulae in the Galactic environment and extragalactic ...

What Does the LMC Look Like? It Depends on [M/H] and Age
The Astrophysical JournalWe offer a new way to look at the LMC through stellar mono-abundance and mono-age mono-abundance maps. These maps are based on ≳500,000 member stars with estimates of [M/H] ( σ _[M/H] ~ 0.17) and age $({\sigma }_{{\rm{log}}\tau }\unicode{x0007E}0.15$ ),

Detection of Metal Enrichment by SN 2011jm in NGC 4809
The Astrophysical Journal LettersCosmic metals are believed to originate from stellar and supernovae (SNe) nucleosynthesis, dispersed into the interstellar medium (ISM) through stellar winds and supernova explosions.

The inclination of the dwarf irregular galaxy Holmberg II
, 2014 We provide constraints on the inclination angle of the H\,{\sc i} disk of the dwarf irregular galaxy Holmberg II (Ho II) from stability analysis of the outer gaseous disk. We point out that a mean inclination angle of 27 degrees and thus a flat circular velocity of ~60 km/s, is required to have a level of gravitational stability similar to that found ...
