Discovery of a tidal dwarf galaxy in the Leo Triplet

, 2014
We report the discovery of a dwarf galaxy in the Leo Triplet. Analysis of the neutral hydrogen distribution shows that it rotates independently of the tidal tail of NGC 3628, with a radial velocity gradient of 35-40 km s^{-1} over approximately 13 kpc ...

Kinematics of the dwarf irregular galaxy GR8

, 2003
We present deep, high velocity resolution (~ 1.6 km s −1) Giant Meterwave Radio Telescope HI 21 cm synthesis images for the faint ( MB ~ −12.1) dwarf irregular galaxy GR8. We find that the velocity field of the galaxy shows a clear systematic large scale

Dwarf and Intermediate-mass Galaxies in MaNGA: Evidence for Different Evolutionary Trends

The Astrophysical Journal
We investigate the interplay between morphology, specific star formation rate (sSFR), and local environment using a sample of 7408 galaxies from the fourth-generation Sloan Digital Sky Survey Mapping Nearby Galaxies at Apache Point Observatory survey ...

SAGAbg. III. Environmental Stellar Mass Functions, Self-quenching, and the Stellar-to-halo Mass Relation in the Dwarf Galaxy Regime

The Astrophysical Journal
Recent efforts have extended our view of the number and properties of satellite galaxies beyond the Local Group firmly down to M _⋆  ∼ 10 ^6 M _⊙ . A similarly complete view of the field dwarf population has lagged behind.

Sagittarius dwarf spheroidal galaxy observed by H.E.S.S

, 2013
In Proceedings of the 33rd International Cosmic Ray Conference (ICRC2013), Rio de Janeiro (Brazil)Dwarf spheroidal galaxies are characterized by a large measured mass-to-light ratio and are not expected to be the site of high-luminosity non-thermal high ...
