CHANG-ES IX: Radio scale heights and scale lengths of a consistent sample of 13 spiral galaxies seen edge-on and their correlations

Marita Krause, Judith Irwin, Theresa Wiegert +14

The vertical halo scale height is a crucial parameter to understand the transport of cosmic-ray electrons (CRE) and their energy loss mechanisms in spiral galaxies. Until now, the…

Stripping of the Hot Gas Halos in Member Galaxies of Abell 1795

Cory R. Wagner, Michael McDonald, Stephane Courteau

The nearby cluster Abell 1795 is used as a testbed to examine whether hot gas in cluster galaxies is stripped by the ram pressure of the intracluster medium (ICM). The expected X-r…

Deep Subaru Hyper Suprime-Cam observations of Milky Way satellites Columba I and Triangulum II

Jeffrey L. Carlin, David J. Sand, Ricardo R. Munoz +9

We present deep, wide-field Subaru Hyper Suprime-Cam photometry of two recently discovered satellites of the Milky Way (MW): Columba I and Triangulum II. The color magnitude diagra…

Atomic Gas in Blue Ultra Diffuse Galaxies around Hickson Compact Groups

Kristine Spekkens, Ananthan Karunakaran

We have found the atomic gas (HI) reservoirs of the blue ultra diffuse galaxy (UDG) candidates identified by Róman and Trujillo in images near Hickson Compact Groups (HCGs). We con…

Spontaneous generation of bending waves in isolated Milky Way-like discs

Matthew H. Chequers, Lawrence M. Widrow

We study the spontaneous generation and evolution of bending waves in -body simulations of two isolated Milky Way-like galaxy models. The models differ by their disc-to-halo mas…

The Green Bank Ammonia Survey: Dense Cores Under Pressure in Orion A

Helen Kirk, Rachel K. Friesen, Jaime E. Pineda +21

We use gas temperature and velocity dispersion data from the Green Bank Ammonia Survey and core masses and sizes from the James Clerk Maxwell Telescope Gould Belt Survey to estimat…

The Next Generation Virgo Cluster Survey. XXVIII. Characterization of the Galactic White Dwarf Population

Nicholas J. Fantin, Patrick Côté, David A. Hanes +6

We use three different techniques to identify hundreds of white dwarf (WD) candidates in the Next Generation Virgo Cluster Survey (NGVS) based on photometry from the NGVS and GUViC…

The Spectroscopy and H-band Imaging of Virgo cluster galaxies (SHIVir) Survey: Scaling Relations and the Stellar-to-Total Mass Relation

Nathalie N. -Q. Ouellette, Stéphane Courteau, Jon A. Holtzman +10

We present here parameter distributions and fundamental scaling relations for 190 galaxies as part of the Spectroscopy and H-bang Imaging of Virgo cluster galaxies (SHIVir) survey.…

Magnetic Spiral Arms in Galaxy Halos

R. N. Henriksen

We seek the conditions for a {\it steady} mean field galactic dynamo. The parameter set is reduced to those appearing in the and dynamo, namely velocity amplitudes, and…

The Green Bank Ammonia Survey (GAS): First Results of NH3 mapping the Gould Belt

Rachel K. Friesen, Jaime E. Pineda, Erik Rosolowsky +21

We present an overview of the first data release (DR1) and first-look science from the Green Bank Ammonia Survey (GAS). GAS is a Large Program at the Green Bank Telescope to map al…
