We present new HI spectral line imaging of the extremely metal-poor, star-forming dwarf irregular galaxy Leo P. Our HI images probe the global neutral gas properties and the local conditions of the interstellar medium (ISM). The HI morphology is slightly elongated along the optical major-axis. We do not find obvious signatures of interaction or infalling gas at large spatial scales. The neutral gas disk shows obvious rotation, although the velocity dispersion is comparable to the rotation… Expand
Rotational Dynamics and Star Formation in the Nearby Dwarf Galaxy NGC 5238
We present new HI spectral line images of the nearby low-mass galaxy NGC 5238, acquired with the Karl G. Jansky Very Large Array (VLA). Located at a distance of 4.51+/-0.04 Mpc, NGC 5238 is anExpand
Leo P: An Unquenched Very Low-Mass Galaxy
Leo P is a low-luminosity dwarf galaxy discovered through the blind HI Arecibo Legacy Fast ALFA (ALFALFA) survey. The HI and follow-up optical observations have shown that Leo P is a gas-rich dwarfExpand
Deep neutral hydrogen observations of Leo T with the Westerbork Synthesis Radio Telescope
Leo T is the lowest mass gas-rich galaxy currently known and studies of its gas content help us understand how such marginal galaxies survive and form stars. We present deep neutral hydrogen (HI)Expand
Asymptotic Giant Branch Stars in the Nearby Dwarf Galaxy Leo P
We have conducted a highly sensitive census of the evolved-star population in the metal-poor dwarf galaxy Leo P and detected four asymptotic giant branch (AGB) star candidates. Leo P is one of theExpand
How the first stars shaped the faintest gas-dominated dwarf galaxies
Low-mass dwarf galaxies are very sensitive test-beds for theories of cosmic structure formation since their weak gravitational fields allow the effects of the relevant physical processes to clearlyExpand
SHIELD: NEUTRAL GAS KINEMATICS and DYNAMICS
We present kinematic analyses of the 12 galaxies in the "Survey of HI in Extremely Low-mass Dwarfs" (SHIELD). We use multi-configuration interferometric observations of the HI 21cm emission line fromExpand
How the first stars shaped the faintest gas-dominated dwarf galaxies
Abstract Cosmological simulations predict that dark matter halos with circular velocities lower than 30 km/s should have lost most of their neutral gas by heating of the ultra-violet background. ThisExpand
First stellar spectroscopy in Leo P
We present the first stellar spectroscopy in the low-luminosity (MV ∼ −9.3 mag), dwarf galaxy Leo P. Its significantly low oxygen abundance (3% solar) and relative proximity (∼1.6 Mpc) make it aExpand
