Hubble Space Telescope Observations of Two Faint Dwarf Satellites of Nearby LMC Analogs from MADCASH
Jeffrey L. Carlin, Burcin Mutlu-Pakdil, Denija Crnojevic +11
We present a deep Hubble Space Telescope (HST) imaging study of two dwarf galaxies in the halos of Local Volume Large Magellanic Cloud (LMC) analogs. These dwarfs were discovered a…
New Evidence for Extended HeII Reionization at z>3.5 from HeII Lyman Alpha and Beta Transmission Spikes
Kirill Makan, Gábor Worseck, Frederick B. Davies +3
We present new high-resolution (R~14,000) spectra of the two brightest HeII-transparent quasars in the far-UV (FUV) at z>3.5, HE2QSJ2311-1417 (z=3.70) and HE2QSJ1630+0435 (z=3.81),…
SDSS-IV MaNGA: Refining Strong Line Diagnostic Classifications Using Spatially Resolved Gas Dynamics
David R. Law, Xihan Ji, Francesco Belfiore +8
We use the statistical power of the MaNGA integral-field spectroscopic galaxy survey to improve the definition of strong line diagnostic boundaries used to classify gas ionization…
Preliminary Target Selection for the DESI Milky Way Survey (MWS)
Carlos Allende Prieto, Andrew P. Cooper, Arjun Dey +31
The DESI Milky Way Survey (MWS) will observe 8 million stars between mag, supplemented by observations of brighter targets under poor observing conditions. The s…
An extremely metal-deficient globular cluster in the Andromeda Galaxy
S. S. Larsen, A. J. Romanowsky, J. P. Brodie +1
Globular clusters (GCs) are dense, gravitationally bound systems of thousands to millions of stars. They are preferentially associated with the oldest components of galaxies, and m…
Stellar Velocity Dispersion and Dynamical Mass of the Ultra-Diffuse Galaxy NGC 5846_UDG1 from the Keck Cosmic Web Imager
Duncan A. Forbes, Jonah S. Gannon, Aaron J. Romanowsky +4
The ultra-diffuse galaxy in the NGC 5846 group (NGC 5846_UDG1) was shown to have a large number of globular cluster (GC) candidates from deep imaging as part of the VEGAS survey. R…
The S2 Stream: the shreds of a primitive dwarf galaxy
David S. Aguado, G. C. Myeong, Vasily Belokurov +12
The S2 stream is a kinematically cold stream that is plunging downwards through the Galactic disc. It may be part of a hotter and more diffuse structure called the Helmi stream. We…
The Size and Pervasiveness of Ly-UV Spatial Offsets in Star-Forming Galaxies at
B. C. Lemaux, S. Fuller, M. Bradač +20
We study the projected spatial offset between the ultraviolet continuum and Ly emission for 65 lensed and unlensed galaxies in the Epoch of Reionization (), the fi…
First results from SMAUG: Insights into star formation conditions from spatially-resolved ISM properties in TNG50
Bhawna Motwani, Shy Genel, Greg L. Bryan +11
Physical and chemical properties of the interstellar medium (ISM) at sub-galactic (kpc) scales play an indispensable role in controlling the ability of gas to form stars. As…
Circumgalactic Mg II Emission from an Isotropic Starburst Galaxy Outflow Mapped by KCWI
Joseph N. Burchett, Kate H. R. Rubin, J. Xavier Prochaska +3
We present spatially-resolved spectroscopy from the Keck Cosmic Web Imager (KCWI) of a star-forming galaxy at z=0.6942, which shows emission from the Mg II 2796, 2803 Angstrom doub…
Fornax 3D project: automated detection of planetary nebulae in the centres of early-type galaxies and first results
T. W. Spriggs, M. Sarzi, R. Napiwotzki +15
Extragalactic planetary nebulae (PNe) are detectable through relatively strong nebulous [OIII] emission and act as direct probes into the local stellar population. Because they hav…
Project AMIGA: The Circumgalactic Medium of Andromeda
Nicolas Lehner, Samantha C. Berek, J. Christopher Howk +22
Project AMIGA (Absorption Maps In the Gas of Andromeda) is a large ultraviolet Hubble Space Telescope program, which has assembled a sample of 43 QSOs that pierce the circumgalacti…
SDSS IV MaNGA -- Metallicity and ionisation parameter in local star-forming galaxies from Bayesian fitting to photoionisation models
M. Mingozzi, F. Belfiore, G. Cresci +15
We measured gas-phase metallicity, ionisation parameter and dust extinction for 1795 representative local star-forming galaxies using integral field spectroscopy from the SDSS-IV M…
Multiwavelength Follow-up of the Hyperluminous Intermediate-mass Black Hole Candidate 3XMM J215022.4-055108
Dacheng Lin, Jay Strader, Aaron J. Romanowsky +6
We recently discovered the X-ray/optical outbursting source 3XMM J215022.4-055108. It was best explained as the tidal disruption of a star by an intermediate-mass black hole of mas…
Asymmetric Drift of Andromeda Analogs in the IllustrisTNG Simulation
Amanda C. N. Quirk, Ekta Patel
We analyze the kinematics as a function of stellar age for Andromeda (M31) mass analogs from the IllustrisTNG cosmological simulation. We divide the star particles into four age gr…
