A tidally disrupting dwarf galaxy in the halo of NGC 253
Elisa Toloba, David Sand, Kristine Spekkens +7
We report the discovery of Scl-MM-Dw2, a new dwarf galaxy at a projected separation of 50 kpc from NGC 253, as part of the PISCeS (Panoramic Imaging Survey of Centaurus and S…
The extended halo of Centaurus A: uncovering satellites, streams, and substructures
D. Crnojević, D. J. Sand, K. Spekkens +7
We present the widest-field resolved stellar map to date of the closest ( Mpc) massive elliptical galaxy NGC 5128 (Centaurus A; Cen A), extending out to a projected galac…
Resolving the extended stellar halos of nearby galaxies: the wide-field PISCeS survey
D. Crnojević, D. J. Sand, N. Caldwell +6
In the wide-field Panoramic Imaging Survey of Centaurus and Sculptor (PISCeS), we investigate the resolved stellar halos of two nearby galaxies (the elliptical Centaurus A and the…
Data Reduction Pipeline for the MMT and Magellan Infrared Spectrograph
Igor Chilingarian, Yuri Beletsky, Sean Moran +3
We describe the new spectroscopic data reduction pipeline for the multi-object MMT/Magellan Infrared Spectrograph. The pipeline is implemented in idl as a stand-alone package and i…
A Comprehensive Archival Search for Counterparts to Ultra-Compact High Velocity Clouds: Five Local Volume Dwarf Galaxies
D. J. Sand, D. Crnojević, P. Bennet +17
We report five Local Volume dwarf galaxies (two of which are presented here for the first time) uncovered during a comprehensive archival search for optical counterparts to ultra-c…
