X-ray and Ultraviolet Properties of AGN in Nearby Dwarf Galaxies
Vivienne F. Baldassare, Amy E. Reines, Elena Gallo +1
We present new Chandra X-ray Observatory and Hubble Space Telescope observations of eight optically selected broad-line AGN candidates in nearby dwarf galaxies (). Includi…
Exploring the Role of Sub-micron Sized Dust Grains in the Atmospheres of Red L0 - L6 Dwarfs
Kay Hiranaka, Kelle L. Cruz, Stephanie T. Douglas +2
We examine the hypothesis that the red near-infrared colors of some L dwarfs could be explained by a "dust haze" of small particles in their upper atmospheres. This dust haze would…
Population Properties of Brown Dwarf Analogs to Exoplanets
Jacqueline K. Faherty, Adric R. Riedel, Kelle L. Cruz +10
We present a kinematic analysis of 152 low surface gravity M7-L8 dwarfs by adding 8 parallaxes, 38 radial velocities, and 19 proper motions. We find 39 objects to be high-likelihoo…
Multi-epoch Spectroscopy of Dwarf Galaxies with AGN Signatures: Identifying Sources with Persistent Broad H-alpha Emission
Vivienne F. Baldassare, Amy E. Reines, Elena Gallo +6
We use time-domain optical spectroscopy to distinguish between broad emission lines powered by accreting black holes (BHs) or stellar processes (i.e., supernovae) for 16 galaxies i…
