The case for inflow of the broad-line region of active galactic nuclei
C. Martin Gaskell, Rene W. Goosmann
The high-ionization lines of the broad-line region (BLR) of thermal active galactic nuclei (AGNs) show blueshifts of a few hundred km/s to several thousand km/sec with respect to t…
Evidence of Fanning in the Ophiuchus Stream
B. Sesar, A. M. Price-Whelan, J. G. Cohen +11
The Ophiuchus stellar stream presents a dynamical puzzle: its old stellar populations ( Gyr) cannot be reconciled with (1) its orbit in a simple model for the Milky Way po…
Satellite accretion in action: a tidally disrupting dwarf spheroidal around the nearby spiral galaxy NGC 253
Aaron J. Romanowsky, D. Martinez-Delgado, Nicolas F. Martin +7
We report the discovery of NGC 253-dw2, a dwarf spheroidal (dSph) galaxy candidate undergoing tidal disruption around a nearby spiral galaxy, NGC 253 in the Sculptor group: the fir…
Feeling the pull, a study of natural Galactic accelerometers. I: photometry of the delicate stellar stream of the Palomar 5 globular cluster
Rodrigo A. Ibata, Geraint F. Lewis, Nicolas F. Martin
We present an analysis of wide-field photometric surveys of the Palomar 5 globular cluster and its stellar stream, based on g- and r-band measures together with narrow-band DDO51 p…
The Transverse velocity of the Andromeda system, derived from the M31 satellite population
J. -B. Salomon, R. A. Ibata, B. Famaey +2
We present a dynamical measurement of the tangential motion of the Andromeda system, the ensemble consisting of the Andromeda Galaxy (M31) and its satellites. The system is modelle…
Major Substructure in the M31 Outer Halo: the East Cloud
B. McMonigal, N. F. Bate, A. R. Conn +8
We present the first detailed analysis of the East Cloud, a highly disrupted diffuse stellar substructure in the outer halo of M31. The core of the substructure lies at a projected…
Cosmic Dawn (CoDa): the First Radiation-Hydrodynamics Simulation of Reionization and Galaxy Formation in the Local Universe
Pierre Ocvirk, Nicolas Gillet, Paul R. Shapiro +12
Cosmic reionization by starlight from early galaxies affected their evolution, thereby impacting reionization, itself. Star formation suppression, for example, may explain the obse…
On the persistence of two small-scale problems in ΛCDM
Marcel S. Pawlowski, Benoit Famaey, David Merritt +1
We investigate the degree to which the inclusion of baryonic physics can overcome two long-standing problems of the standard cosmological model on galaxy scales: (i) the problem of…
Dynamical measurement of the stellar surface density of face-on galaxies
Garry W. Angus, Gianfranco Gentile, Benoit Famaey
The DiskMass survey recently provided measurements of the vertical velocity dispersions of disk stars in a sample of nearly face-on galaxies. By setting the disk scale-heights to b…
Unveiling a Rich System of Faint Dwarf Galaxies in the Next Generation Fornax Survey
Roberto P. Munoz, Paul Eigenthaler, Thomas H. Puzia +18
We report the discovery of 158 previously undetected dwarf galaxies in the Fornax cluster central regions using a deep coadded and -band image obtained with the DECam wid…
Combined Solar System and rotation curve constraints on MOND
A. Hees, B. Famaey, G. W. Angus +1
The Modified Newtonian Dynamics (MOND) paradigm generically predicts that the external gravitational field in which a system is embedded can produce effects on its internal dynamic…
The Relationship Between Molecular Gas, HI, and Star Formation in the Low-Mass, Low-Metallicity Magellanic Clouds
Katherine E. Jameson, Alberto D. Bolatto, Adam K. Leroy +14
The Magellanic Clouds provide the only laboratory to study the effect of metallicity and galaxy mass on molecular gas and star formation at high (~20 pc) resolution. We use the dus…
Variable stars in the field of the Hydra II ultra-faint dwarf galaxy
A. Katherina Vivas, Knut Olsen, Robert Blum +12
We report the discovery of one RR Lyrae star in the ultra--faint satellite galaxy Hydra II based on time series photometry in the g, r and i bands obtained with the Dark Energy Cam…
Triangulum II: a very metal-poor and dynamically hot stellar system
Nicolas F. Martin, Rodrigo A. Ibata, Michelle L. M. Collins +7
We present a study of the recently discovered compact stellar system Triangulum II. From observations conducted with the DEIMOS spectrograph on Keck II, we obtained spectra for 13…
Is Draco II one of the faintest dwarf galaxies? First study from Keck/DEIMOS spectroscopy
Nicolas F. Martin, Marla Geha, Rodrigo A. Ibata +8
We present the first spectroscopic analysis of the faint and compact stellar system Draco II (Dra II, M_V=-2.9+/-0.8, r_h=19^{+8}_{-6} pc), recently discovered in the Pan-STARRS1 3…
Extended Lyman alpha haloes around individual high-redshift galaxies revealed by MUSE
L. Wisotzki, R. Bacon, J. Blaizot +22
We report the detection of extended Ly alpha emission around individual star-forming galaxies at redshifts z = 3-6 in an ultradeep exposure of the Hubble Deep Field South obtained…
