A Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE).I. Introduction to the Survey
A. Boselli, M. Fossati, L. Ferrarese +56
The Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE) is a blind narrow-band Halpha+[NII] imaging survey carried out with MegaCam at the Canada-France-Hawaii Telesc…
Shock-Enhanced C+ Emission and the Detection of H2O from Stephan's Quintet's Group-Wide Shock using Herschel
P. N. Appleton, P. Guillard, F. Boulanger +20
We present the first Herschel spectroscopic detections of the [OI]63 and [CII]158 micron fine-structure transitions, and a single para-H2O line from the 35 x 15 kpc^2 shocked inter…
The role of molecular gas in galaxy transition in compact groups
U. Lisenfeld, K. Alatalo, C. Zucker +4
Compact groups (CGs) provide an environment in which interactions between galaxies and with the intra-group medium enable and accelerate galaxy transitions from actively star formi…
Discovery of Probable Relativistic Fe Emission and Absorption in the Cloverleaf Quasar H 1413+117
G. Chartas, M. Eracleous, X. Dai +2
We present results from Chandra and XMM-Newton observations of the low-ionization broad absorption line (LoBAL) quasar H 1413+117. Our spatial and spectral analysis of a recent dee…
Herschel Spectroscopy of the Taffy Galaxies (UGC 12914/12915 = VV 254): Enhanced [C II] emission in the collisionally-formed bridge
B. W. Peterson, P. N. Appleton, T. Bitsakis +17
Using the PACS and SPIRE spectrometers on-board Herschel, we obtained observations of the Taffy galaxies (UGC 12914/12915) and bridge. The Taffy system is believed to be the result…
The X-Rays wind connection in PG 2112+059
C. Saez, W. N. Brandt, F. Bauer +4
We study the connection between the X-ray and UV properties of the broad absorption line (BAL) wind in the highly X-ray variable quasar PG 2112+059 by comparing Chandra-ACIS data w…
The Beginning of the End: Hubble Space Telescope Images of Seyfert's Sextet
C. Palma, S. Zonak, S. Hunsberger +4
Hubble Space Telescope Wide Field Planetary Camera 2 images of Hickson Compact Group 79, Seyfert's Sextet, are presented. Both point sources and extended sources detected on the th…
Multi-phase gas interactions on subarcsec scales in the shocked IGM of Stephan's Quintet with JWST and ALMA
P. N. Appleton, P. Guillard, B. Emonts +12
We combine JWST and HST imaging with ALMA~CO(2-1) spectroscopy to study the highly turbulent multi-phase intergalactic medium (IGM) in Stephan's Quintet on 25-150 pc scales. Previo…
Results from an extensive simultaneous broadband campaign on the underluminous active nucleus M81*: further evidence for mass-scaling accretion in black holes
S. Markoff, M. Nowak, A. Young +13
We present the results of a broadband simultaneous campaign on the nearby low-luminosity active galactic nucleus M81*. From February through August 2005, we observed M81* five time…
The Evolution of Galaxy Clusters Across Cosmic Time
M. Arnaud, H. Bohringer, C. Jones +40
The large scale structure of the present Universe is determined by the growth of dark matter density fluctuations and by the dynamical action of dark energy and dark matter. While…
Gemini Spectroscopic Survey of Young Star Clusters in Merging/Interacting Galaxies. IV. Stephan's Quintet
G. Trancho, I. Konstantopoulos, N. Bastian +4
We present a spectroscopic survey of 21 young massive clusters and complexes and one tidal dwarf galaxy candidate (TDG) in Stephan's Quintet, an interacting compact group of galaxi…
The Hot and Energetic Universe: Astrophysics of feedback in local AGN
M. Cappi, C. Done, E. Behar +30
Understanding the astrophysics of feedback in active galactic nuclei (AGN) is key to understanding the growth and co-evolution of supermassive black holes and galaxies. AGN-driven…
