Reading Between the (Spectral) Lines: Magellan/IMACS spectroscopy of the Ultra-faint Dwarf Galaxies Eridanus IV and Centaurus I
M. E. Heiger, T. S. Li, A. B. Pace +17
We present a spectroscopic analysis of Eridanus IV (Eri IV) and Centaurus I (Cen I), two ultra-faint dwarf galaxies of the Milky Way. Using IMACS/Magellan spectroscopy, we identify…
DELVE 6: An Ancient, Ultra-Faint Star Cluster on the Outskirts of the Magellanic Clouds
W. Cerny, A. Drlica-Wagner, T. S. Li +23
We present the discovery of DELVE 6, an ultra-faint stellar system identified in the second data release of the DECam Local Volume Exploration (DELVE) survey. Based on a maximum-li…
Identification of Galaxy-Galaxy Strong Lens Candidates in the DECam Local Volume Exploration Survey Using Machine Learning
E. A. Zaborowski, A. Drlica-Wagner, F. Ashmead +88
We perform a search for galaxy-galaxy strong lens systems using a convolutional neural network (CNN) applied to imaging data from the first public data release of the DECam Local V…
Six More Ultra-Faint Milky Way Companions Discovered in the DECam Local Volume Exploration Survey
W. Cerny, C. E. Martínez-Vázquez, A. Drlica-Wagner +28
We report the discovery of six ultra-faint Milky Way satellites discovered through matched-filter searches conducted using Dark Energy Camera (DECam) data processed as part of the…
Pegasus IV: Discovery and Spectroscopic Confirmation of an Ultra-Faint Dwarf Galaxy in the Constellation Pegasus
W. Cerny, J. D. Simon, T. S. Li +29
We report the discovery of Pegasus IV, an ultra-faint dwarf galaxy found in archival data from the Dark Energy Camera processed by the DECam Local Volume Exploration Survey. Pegasu…
The synchronised dance of the Magellanic Clouds' star formation history
P. Massana, T. Ruiz-Lara, N. E. D. Noël +17
We use the SMASH survey to obtain unprecedented deep photometry reaching down to the oldest main sequence turn-offs in the colour-magnitude diagrams (CMDs) of the Small Magellanic…
Eridanus IV: an Ultra-Faint Dwarf Galaxy Candidate Discovered in the DECam Local Volume Exploration Survey
W. Cerny, A. B. Pace, A. Drlica-Wagner +29
We present the discovery of a candidate ultra-faint Milky Way satellite, Eridanus IV (DELVE J05050931), detected in photometric data from the DECam Local Volume Exploration surv…
RR Lyrae stars in the newly discovered ultra-faint dwarf galaxy Centaurus I
C. E. Martínez-Vázquez, W. Cerny, A. K. Vivas +22
We report the detection of three RR Lyrae (RRL) stars (two RRc and one RRab) in the ultra-faint dwarf (UFD) galaxy Centaurus I (CenI) and two Milky Way (MW) Scuti/SX Phoenicis…
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…
Water in star-forming regions (WISH): Physics and chemistry from clouds to disks as probed by Herschel spectroscopy
E. F. van Dishoeck, L. E. Kristensen, the WISH team
(abridged) Data and results from the WISH key program are summarized, designed to provide a legacy data set to address its physics and chemistry. WISH targeted ~80 sources along th…
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…
Identification of the Hard X-ray Source Dominating the E > 25 keV Emission of the Nearby Galaxy M31
M. Yukita, A. Ptak, A. E. Hornschemeier +15
We report the identification of a bright hard X-ray source dominating the M31 bulge above 25 keV from a simultaneous NuSTAR-Swift observation. We find that this source is the count…
Observations of water with Herschel/HIFI toward the high-mass protostar AFGL 2591
Y. Choi, F. F. S. van der Tak, E. F. van Dishoeck +2
Water is a sensitive tracer of physical conditions in star-forming regions because of its large abundance variations between hot and cold regions. We use spectrally resolved observ…
A non-equilibrium ortho-to-para ratio of water in the Orion PDR
Y. Choi, F. F. S. van der Tak, E. A. Bergin +1
The ortho-to-para ratio (OPR) of HO is thought to be sensitive to the temperature of water formation. The OPR of HO is thus useful to study the formation mechanism of water…
Trigonometric Parallaxes of Star Forming Regions in the Perseus Spiral Arm
Y. K. Choi, K. Hachisuka, M. J. Reid +4
We report trigonometric parallaxes and proper motions of water masers for 12 massive star forming regions in the Perseus spiral arm of the Milky Way as part of the Bar and Spiral S…
