The Limb Shift Effect and its Variation with the Solar Cycle
The radial velocity limb shift effect has been measured for the K I 7699 Å line using a resonant scattering spectrophotometer in the summer of 1982. On the...
The Lines are Not Fine: Measuring Vanadium Abundances in M dwarfs from Hyperfine-Split Lines
Cool star atmospheres present challenges to chemical abundance studies. To date, only a handful of elements have been quantified for a handful of M dwarfs. In...
The Lithium-, r- and s-Enhanced Metal-Poor Giant HK-II 17435-00532
We present the first detailed abundance analysis of the metal-poor giant HK-II 17435-00532. This star was observed as part of the University of Texas Long-Term...
The LMT Galaxies' 3 mm Spectroscopic Survey: First Results
The molecular phase of the interstellar medium (ISM) in galaxies offers fundamental insight for understanding star-formation processes and how stellar feedback...
The Local Black Hole - Mass Function Derived from Spiral Galaxies
Here we present our determination of the black hole - mass function for spiral galaxies in our local universe. We have established our black hole - mass...
The Local Group Dwarf Irregular Galaxy NGC 6822: new insight on its star formation history .
We present a new photometric analysis of the Local Group Dwarf Irregular Galaxy NGC 6822 based on archival Hubble Space Telescope Advanced Camera for Surveys...
The Local Interstellar Medium - A test-bed for the galactic ISM
A method to explore the column density of the Local Interstellar Medium (LISM) using absorptions in the resonance H and K lines of Mg II. The intrinsic...
