An Initial Look at the Far Infrared-Radio Correlation within Nearby Star-forming Galaxies using the Spitzer Space Telescope
E. J. Murphy, R. Braun, G. Helou +25
(Abridged) We present an initial look at the far infrared-radio correlation within the star-forming disks of four nearby, nearly face-on galaxies (NGC 2403, NGC 3031, NGC 5194, and…
The gaseous haloes of disc galaxies
F. Fraternali, T. Oosterloo, J. J. Binney +1
The study of gas outside the plane of disc galaxies is crucial to understanding the circulation of material within a galaxy and between galaxies and the intergalactic environment.…
The very late-stage merger IC 4200:pre-elliptical or pre-spiral?
P. Serra, S. C. Trager, J. M. van der Hulst +3
Recent observations have revealed a class of unusually HI-rich early-type galaxies. By combining observations of their morphology, stellar populations and neutral hydrogen we aim t…
Merger-origin of radio galaxies investigated with H I observations
B. H. C. Emonts, R. Morganti, T. A. Oosterloo +4
We present results of an HI study of a complete sample of nearby radio galaxies. Our goal is to investigate whether merger or interaction events could be at the origin of the radio…
A dark jet dominates the power output of the stellar black hole Cygnus X-1
E. Gallo, R. Fender, C. Kaiser +4
Accreting black holes are thought to emit the bulk of their power in the X-ray band by releasing the gravitational potential energy of the infalling matter. At the same time, they…
The Faint End of the HI Mass Function
K. Kovac, T. A. Oosterloo, J. M. van der Hulst
We study the faint end of the HI mass function (HIMF) in order to test the predictions of the CDM theory on the number density of objects with small (dark) masses. The neutral hydr…
A jet-induced outflow of warm gas in 3C 293
B. H. C. Emonts, R. Morganti, C. N. Tadhunter +3
Using long slit emission-line spectra we detect a fast outflow of ionized gas, with velocities up to 1000 km/s, in the nearby powerful radio galaxy 3C 293 (z = 0.045). The fast out…
Fast outflow of neutral and ionized gas from the radio galaxy 3C 293
B. H. C. Emonts, R. Morganti, T. A. Oosterloo +2
We detect a fast outflow of neutral and ionized gas with velocities up to about 1000 km/s from the central region of radio galaxy 3C 293. With optical spectroscopy we locate the bu…
The HIPASS Catalogue: III - Optical Counterparts & Isolated Dark Galaxies
Marianne T. Doyle, M. J. Drinkwater, D. J. Rohde +38
We present the largest catalogue to date of optical counterparts for HI radio-selected galaxies, Hopcat. Of the 4315 HI radio-detected sources from the HI Parkes All Sky Survey (Hi…
A large HI cloud near the centre of the Virgo cluster
Tom Oosterloo, Jacqueline van Gorkom
We report the discovery of a large HI cloud in the central regions of the Virgo cluster. It is 110 x 25 kpc in size and contains 3.4 x 10^8 Msol of HI. The morphology and kinematic…
The location of the broad HI absorption in 3C305: clear evidence for a jet-accelerated neutral outflow
R. Morganti, T. A. Oosterloo, C. N. Tadhunter +2
We present high-spatial resolution 21-cm HI VLA observations of the radio galaxy 3C305 (z=0.041). These new high-resolution data show that the ~1000 km/s broad HI absorption, earli…
Extra-planar gas in the spiral galaxy NGC 4559
C. V. Barbieri, F. Fraternali, T. Oosterloo +3
We present 21-cm line observations of the spiral galaxy NGC 4559, made with the Westerbork Synthesis Radio Telescope. We have used them to study the HI distribution and kinematics,…
