VLT-VIMOS integral field spectroscopy of luminous and ultraluminous infrared galaxies. I. The sample and first results
Santiago Arribas, Luis Colina, Ana Monreal-Ibero +3
(Ultra)Luminous Infrared Galaxies [(U)LIRGs] are much more numerous at cosmological distances than locally, and are likely precursors of elliptical galaxies. Our goal is to carry o…
Search for Tidal Dwarf Galaxies Candidates in a Sample of Ultraluminous Infrared Galaxies
A. Monreal-Ibero, L. Colina, S. Arribas +1
(ABRIDGED) Star-forming small galaxies made out of collisional debris have been found in a variety of merging systems. So far only a few of them are known in ULIRGs although they s…
Integral field spectroscopy of the Luminous Infrared Galaxy Arp299 (IC694+NGC3690)
Macarena Garcia-Marin, Luis Colina, Santiago Arribas +2
The luminous infrared galaxy Arp299 (IC694+NGC3690) is studied using optical integral field spectroscopy obtained with the INTEGRAL system, together with archival Hubble Space Tele…
Exploring the Potential of Integral Field Spectroscopy Observing Extrasolar Planet Transits: Ground Based Observations of the Atmospheric Na in HD209458b
Santiago Arribas, Ronald L. Gilliland, William B. Sparks +4
We explore the use of Integral Field Spectroscopy (IFS) to observe extrasolar planet transits. Although this technique should find its full potential in space observations (e.g. JW…
Asymmetrical structure of ionization and kinematics in the Seyfert galaxy NGC 5033
E. Mediavilla, A. Guijarro, A. Castillo-Morales +5
We present integral field spectroscopy of NGC 5033, a low luminosity Seyfert galaxy. The observations were made with INTEGRAL, a fiber based system operating at the WHT. The intens…
Optical Imaging of Very Luminous Infrared Galaxy Systems: Photometric Properties and Late Evolution
Santiago Arribas, Howard Bushouse, Ray A. Lucas +2
A sample of 19 low redshift (0.03z0.07) very luminous infrared galaxy (VLIRG: L[8-1000 m] ) systems (30 galaxies) has been imaged in…
The X-Ray Binary X2127+119 in M15: Evidence for a Very-Low-Mass, Stripped-Giant Companion
L. van Zyl, P. A. Charles, S. Arribas +3
We present integral field spectroscopy of X2127+119, the luminous X-ray binary in the globular cluster M15, obtained with INTEGRAL/WYFFOS on the William Herschel Telescope. We find…
INTEGRAL Field Spectroscopy of the Extended Ionized Gas in Arp 220
L. Colina, S. Arribas, D. Clements
Integral field optical spectroscopy with the INTEGRAL system has been used to investigate for the first time the two-dimensional kinematic and ionization properties of the extended…
INTEGRAL Spectroscopy of IRAS 17208-0014: Implications for the Evolutionary Scenarios of Ultraluminous Infrared Galaxies
S. Arribas, L. Colina
New integral field optical fiber spectroscopy obtained with the INTEGRAL system, together with archival {\it {\it HST}} WFPC2 and NICMOS images, have been used to investigate the u…
Chandra Observations of Extended X-ray Emission in Arp 220
J. C. McDowell, D. L. Clements, S. A. Lamb +7
We resolve the extended X-ray emission from the prototypical ultraluminous infrared galaxy Arp 220. Extended, faint edge-brightened, soft X-ray lobes outside the optical galaxy are…
Is a minor-merger driving the nuclear activity in the Seyfert 2 galaxy NGC 2110?
Rosa M. Gonzalez Delgado, Santiago Arribas, Enrique Perez +1
We report on a detailed morphological and kinematic study of the isolated non-barred nearby Seyfert 2 galaxy NGC 2110. We combine Integral Field optical spectroscopy, with long-sli…
The Diverse Population of ULIRGs
K. D. Borne, S. Arribas, H. Bushouse +2
We present results from an on-going Hubble Space Telescope (HST) survey of a large sample of ULIRGs (Ultra-Luminous IR Galaxies). New ground-based observations are now being used t…
Detection and Mapping of Decoupled Stellar and Ionized Gas Structures in the Ultraluminous Infrared Galaxy IRAS 12112+0305
Luis Colina, Santiago Arribas, Kirk D. Borne +1
Integral field optical spectroscopy with the INTEGRAL fiber-fed system and HST optical imaging are used to map the complex stellar and warm ionized gas structure in the ultralumino…
