Pavo: Discovery of a Star-forming Dwarf Galaxy Just Outside the Local Group
The Astrophysical Journal Letters, 2023 We report the discovery of Pavo, a faint ( M _V = −10.0), star-forming, irregular, and extremely isolated dwarf galaxy at D ≈ 2 Mpc. Pavo was identified in Dark Energy Camera Legacy Survey imaging via a novel approach that combines low surface brightness

Citizen Science Time Domain Astronomy with Astro-COLIBRI
, 2023 Astro-COLIBRI is an innovative tool designed for professional astronomers to facilitate the study of transient astronomical events. Transient events - such as supernovae, gamma-ray bursts and stellar mergers - are fleeting cataclysmic phenomena that can offer profound insights into the most violent processes in the universe.

FERMI GBM CAPABILITIES FOR MULTI-MESSENGER TIME-DOMAIN ASTRONOMY [PDF]
EAS Publications Series, 2013 Owing to its wide sky coverage and broad energy range, the Fermi Gamma-ray Burst Monitor (GBM) is an excellent observer of the transient hard X-ray sky. GBM detects about 240 triggered Gamma-Ray Bursts (GRBs) per year, including over 30 which also trigger the Swift Burst Alert Telescope (BAT).

Revisiting the Milky Way stellar long bar and the 3 kpc arm★
Astronomy & AstrophysicsContext. One of the most difficult and unexplored regions of the Milky Way is the highly extincted in-plane central region within the Galactic coordinates 10◦ ≲ |ℓ| ≲ 30◦, |b| ≲ 3◦, where we have the long-bar and 3 kpc arm with intermediate-age stellar ...
