Hubble Space Telescope Observations of Accretion-Induced Star Formation in the Tadpole Galaxy Kiso 5639
Debra Meloy Elmegreen, Bruce G. Elmegreen, Jorge Sanchez Almeida +6
The tadpole galaxy Kiso 5639 has a slowly rotating disk with a drop in metallicity at its star-forming head, suggesting that star formation was triggered by the accretion of metal-…
The nearest ultra diffuse galaxy: UGC2162
Ignacio Trujillo, Javier Román, Mercedes Filho +1
We describe the structural, stellar population and gas properties of the nearest Ultra Diffuse Galaxy (UDG) discovered so far: UGC2162 (z=0.00392; R=1.70.2) kpc; $μ_…
A distance of 13 Mpc resolves the claimed anomalies of the galaxy lacking dark matter
Ignacio Trujillo, Michael A. Beasley, Alejandro Borlaff +10
The claimed detection of a diffuse galaxy lacking dark matter represents a possible challenge to our understanding of the properties of these galaxies and galaxy formation in gener…
Characterizing the local relation between star formation rate and gas-phase metallicity in MaNGA spiral galaxies
Laura Sánchez-Menguiano, Jorge Sánchez Almeida, Casiana Muñoz-Tuñón +4
The role of gas accretion in galaxy evolution is still a matter of debate. The presence of inflows of metal-poor gas that trigger star formation bursts of low metallicity has been…
