Planets Around Low-Mass Stars (PALMS). V. Age-Dating Low-Mass Companions to Members and Interlopers of Young Moving Groups
Brendan P. Bowler, Evgenya L. Shkolnik, Michael C. Liu +22
We present optical and near-infrared adaptive optics (AO) imaging and spectroscopy of 13 ultracool (>M6) companions to late-type stars (K7-M4.5), most of which have recently been i…
The Stellar Spectral Features of Nearby Galaxies in the Near-Infrared: Tracers of Thermally-Pulsing Asymptotic Giant Branch Stars?
Rogério Riffel, Rachel E. Mason, Lucimara P. Martins +12
We analyze the stellar absorption features in high signal-to-noise ratio near-infrared (NIR) spectra of the nuclear region of 12 nearby galaxies, mostly spirals. The features detec…
Hydra II: a faint and compact Milky Way dwarf galaxy found in the Survey of the Magellanic Stellar History
Nicolas F. Martin, David L. Nidever, Gurtina Besla +26
We present the discovery of a new dwarf galaxy, Hydra II, found serendipitously within the data from the ongoing Survey of the MAgellanic Stellar History (SMASH) conducted with the…
The Brightening of Re50N: Accretion Event or Dust Clearing?
Hsin-Fang Chiang, Bo Reipurth, Josh Walawender +5
The luminous Class I protostar HBC 494, embedded in the Orion A cloud, is associated with a pair of reflection nebulae, Re50 and Re50N, which appeared sometime between 1955 and 197…
The Nuclear Near-Infrared Spectral Properties of Nearby Galaxies
R. E. Mason, A. Rodriguez-Ardila, L. Martins +15
We present spectra of the nuclear regions of 50 nearby (D = 1 - 92 Mpc, median = 20 Mpc) galaxies of morphological types E to Sm. The spectra, obtained with the Gemini Near-IR Spec…
The "Green Bean" Galaxy SDSS J224024.1--092748: Unravelling the emission signature of a quasar ionization echo
Rebecca L. Davies, Mischa Schirmer, James E. H. Turner
"Green Bean" Galaxies (GBs) are the most [O III]-luminous type-2 active galactic nuclei (AGN) at z~0.3. However, their infrared luminosities reveal AGN in very low activity states,…
