Investigating the Dark Matter Halo of NGC 5128 using a Discrete Dynamical Model
Antoine Dumont, Anil C. Seth, Jay Strader +7
As the nearest accessible massive early-type galaxy, NGC 5128 presents an exceptional opportunity to measure dark matter halo parameters for a representative elliptical galaxy. Her…
Short Timescale Evolution of the Polarized Radio Jet during V404 Cygni's 2015 Outburst
Andrew K. Hughes, Gregory R. Sivakoff, Christopher E. Macpherson +18
We present a high time resolution, multi-frequency linear polarization analysis of Very Large Array (VLA) radio observations during some of the brightest radio flaring (~1 Jy) acti…
New Velocity Measurements of NGC 5128 Globular Clusters out to 130 kpc: Outer Halo Kinematics, Substructure and Dynamics
A. K. Hughes, D. J. Sand, A. Seth +11
We present new radial velocity measurements from the Magellan and the Anglo-Australian Telescopes for 174 previously known and 122 newly confirmed globular clusters (GCs) around NG…
1RXH J082623.6-505741: a new long-period cataclysmic variable with an evolved donor and a low mass transfer rate
Kirill V. Sokolovsky, Jay Strader, Samuel J. Swihart +13
We report the discovery of 1RXH J082623.6-505741, a 10.4 hr orbital period compact binary. Modeling extensive optical photometry and spectroscopy reveals a K-t…
A population of luminous globular clusters and stripped nuclei with elevated mass to light ratios around NGC 5128
Antoine Dumont, Anil C. Seth, Jay Strader +8
The dense central regions of tidally disrupted galaxies can survive as ultra-compact dwarfs (UCDs) that hide among the luminous globular clusters (GCs) in the halo of massive galax…
NGC 5128 globular cluster candidates out to 150 kpc: a comprehensive catalog from Gaia and ground based data
Allison K. Hughes, David J. Sand, Anil Seth +9
We present a new catalog of 40502 globular cluster (GC) candidates in NGC 5128 out to a projected radius of 150 kpc, based on data from the Panoramic Imaging Survey of Centau…
The DECam Local Volume Exploration Survey: Overview and First Data Release
A. Drlica-Wagner, J. L. Carlin, D. L. Nidever +67
The DECam Local Volume Exploration survey (DELVE) is a 126-night survey program on the 4-m Blanco Telescope at the Cerro Tololo Inter-American Observatory in Chile. DELVE seeks to…
A Gaia-based catalog of candidate stripped nuclei and luminous globular clusters in the halo of Centaurus A
Karina T. Voggel, Anil C. Seth, David J. Sand +4
Tidally stripped galaxy nuclei and luminous globular clusters (GCs) are important tracers of the halos and assembly histories of nearby galaxies, but are difficult to reliably iden…
Two Ultra-Faint Milky Way Stellar Systems Discovered in Early Data from the DECam Local Volume Exploration Survey
S. Mau, W. Cerny, A. B. Pace +56
We report the discovery of two ultra-faint stellar systems found in early data from the DECam Local Volume Exploration survey (DELVE). The first system, Centaurus I (DELVE J1238-40…
The Extremely Luminous Quasar Survey in the Pan-STARRS 1 Footprint (PS-ELQS)
Jan-Torge Schindler, Xiaohui Fan, Yun-Hsin Huang +7
We present the results of the Extremely Luminous Quasar Survey in the survey of the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS; PS1). This effort applies…
A Deeper Look at the New Milky Way Satellites: Sagittarius II, Reticulum II, Phoenix II, and Tucana III
Burçin Mutlu-Pakdil, David J. Sand, Jeffrey L. Carlin +6
We present deep Magellan/Megacam stellar photometry of four recently discovered faint Milky Way satellites: Sagittarius II (Sgr II), Reticulum II (Ret II), Phoenix II (Phe II), and…
