HALOGAS: HI Observations and Modeling of the Nearby Edge-on Spiral Galaxy NGC 4565
Laura K. Zschaechner, Richard J. Rand, George H. Heald +2
We present 21-cm observations and models of the neutral hydrogen in NGC 4565, a nearby, edge-on spiral galaxy, as part of the Westerbork Hydrogen Accretion in LOcal GAlaxieS (HALOG…
The dust energy balance in the edge-on spiral galaxy NGC 4565
Ilse De Looze, Maarten Baes, George J. Bendo +20
We combine new dust continuum observations of the edge-on spiral galaxy NGC 4565 in all Herschel/SPIRE (250, 350, 500 micron) wavebands, obtained as part of the Herschel Reference…
Isolated and non-isolated dwarfs in terms of modified Newtonian dynamics
G. Gentile, G. W. Angus, B. Famaey +2
Within the framework of modified Newtonian dynamics (MOND) we investigate the kinematics of two dwarf spiral galaxies belonging to very different environments, namely KK 246 in the…
The Herschel Exploitation of Local Galaxy Andromeda (HELGA) II: Dust and Gas in Andromeda
M. W. L. Smith, S. A. Eales, H. L. Gomez +26
We present an analysis of the dust and gas in Andromeda, using Herschel images sampling the entire far-infrared peak. We fit a modified-blackbody model to ~4000 quasi-independent p…
Can dust emission be used to map the interstellar medium in high-redshift galaxies? Results from the Herschel Reference Survey
Stephen Eales, Matthew W. L. Smith, Robbie Auld +23
It has often been suggested that an alternative to the standard CO/21-cm method for estimating the mass of the interstellar medium (ISM) in a galaxy might be to estimate the mass o…
A QUMOND galactic N-body code I: Poisson solver and rotation curve fitting
Garry W. Angus, Kurt van der Heyden, Benoit Famaey +3
Here we present a new particle-mesh galactic N-body code that uses the full multigrid algorithm for solving the modified Poisson equation of the Quasi Linear formulation of Modifie…
