The Local Ultraviolet to Infrared Treasury. I. Survey Overview of the Broadband Imaging

The Astrophysical Journal Supplement Series
The Local Ultraviolet to Infrared Treasury (LUVIT) is a Hubble Space Telescope program that combines newly acquired data in the near-ultraviolet (NUV), optical, and near-infrared (NIR) with archival optical and NIR imaging to produce multiband ...

VLT Spectroscopy of Globular Clusters in Low Surface Brightness Dwarf Galaxies

, 2007
We present VLT/FORS2 spectroscopic observations of globular clusters (GCs) in five low surface brightness (LSB) dwarf galaxies: KK211 and KK221, which are both dwarf spheroidal satellites (dSph) of NGC 5128, dSph KK84 located close to the isolated S0 ...

Discovery of Metal-poor and Distant Pre–Main Sequence Candidates in WLM with JWST

The Astrophysical Journal Letters
We present the discovery of 12 metal-poor and ​​​distant pre–main sequence (PMS) candidates in the dwarf irregular galaxy Wolf–Lundmark–Melotte ∼968 kpc away, at a present-day metallicity of [Fe/H] ∼ –0.9.

The K luminosity-metallicity relation for dwarf galaxies and the tidal dwarf galaxies in the tails of HCG 31

, 2006
We determine a K-band luminosity-metallicity (K-Z) relation for dwarf irregular galaxies, over a large range of magnitudes, -20.5 < M_K < -13.5, using a combination of K photometry from either the 2-micron all sky survey (2MASS) or the recent study of ...
