Ground-based variability surveys towards Centaurus A: worthwhile or not?

Jelte T. A. de Jong, Konrad H. Kuijken, Philippe Heraudeau

Context: Difference imaging has proven to be a powerful technique for detecting and monitoring the variability of unresolved stellar sources in M 31. Using this technique in survey…

HST NIR Snapshot Survey of 3CR Radio Source Counterparts II: An Atlas and Inventory of the Host Galaxies, Mergers and Companions

David J. E. Floyd, David Axon, Stefi Baum +10

We present the second part of an H-band (1.6 microns) atlas of z<0.3 3CR radio galaxies, using the Hubble Space Telescope Near Infrared Camera and Multi-Object Spectrometer (HST NI…

The c2d Spitzer spectroscopic survey of ices around low-mass young stellar objects II: CO2

Klaus M. Pontoppidan, A. C. A. Boogert, Helen J. Fraser +6

This paper presents Spitzer-IRS spectroscopy of the CO2 15.2 micron bending mode toward a sample of 50 embedded low-mass stars in nearby star-forming clouds, taken mostly from the…

Spatially Resolved Spitzer-IRS Spectroscopy of the Central Region of M82

P. Beirão, B. R. Brandl, P. N. Appleton +6

We present high spatial resolution (~ 35 parsec) 5-38 um spectra of the central region of M82, taken with the Spitzer Infrared Spectrograph. From these spectra we determined the fl…

A Population of Faint Extended Line Emitters and the Host Galaxies of Optically Thick QSO Absorption Systems

Michael Rauch, Martin Haehnelt, Andrew Bunker +10

We have conducted a long slit search for low surface brightness Lyman-alpha emitters at redshift 2.67 < z < 3.75. A 92 hour long exposure with VLT/FORS2 down to a 1-sigma surface b…

Self-gravitating fragmentation of eccentric accretion disks

R. D. Alexander, P. J. Armitage, J. Cuadra +1

We consider the effects of eccentricity on the fragmentation of gravitationally unstable accretion disks, using numerical hydrodynamics. We find that eccentricity does not affect t…
