The ACS Survey of Galactic Globular Clusters. VII. Relative Ages
Antonio Marin-Franch, Antonio Aparicio, Giampaolo Piotto +13
The ACS Survey of Galactic Globular Clusters is a Hubble Space Telescope (HST) Treasury program designed to provide a new large, deep and homogeneous photometric database. Based on…
The Role of Massive Agb Stars in the Early Solar System Composition
Josep M. Trigo-Rodriguez, Domingo Anibal Garcia-Hernandez, Maria Lugaro +4
We demonstrate that a massive asymptotic giant branch (AGB) star is a good candidate as the main source of short-lived radionuclides in the early solar system. Recent identificatio…
Optimal filter systems for photometric redshift estimation
N. Benitez, M. Moles, J. A. L. Aguerri +18
In the next years, several cosmological surveys will rely on imaging data to estimate the redshift of galaxies, using traditional filter systems with 4-5 optical broad bands; narro…
Three-dimensional Radiative Transfer Modeling of the Polarization of the Sun's Continuous Spectrum
J. Trujillo Bueno, N. Shchukina
Here we formulate and solve the 3D radiative transfer problem of the polarization of the solar continuous radiation. Our approach takes into account not only the anisotropy of the…
A pilot survey of stellar tidal streams in nearby spiral galaxies
David Martinez-Delgado, R. Jay Gabany, Jorge Penarrubia +4
Within the hierarchical framework for galaxy formation, merging and tidal interactions are expected to shape large galaxies to this day. While major mergers are quite rare at prese…
Properties of the ionized gas in HH202. I: Results from integral field spectroscopy with PMAS
A. Mesa-Delgado, L. López-Martín, C. Esteban +2
We present results from integral field spectroscopy with the Potsdam multi-Aperture Spectrograph of the head of the Herbig-Haro object HH 202 with a spatial sampling of 1"x1". We h…
MAGIC Observations of PG 1553+113 during a Multiwavelength Campaign in July 2006
MAGIC Collaboration, Albert
The active galactic nucleus PG 1553+113 was observed by the MAGIC telescope in July 2006 during a multiwavelength campaign, in which telescopes in the optical, X-ray, and very high…
On the Nature of Fossil Galaxy Groups: Are they really fossils ?
F. La Barbera, R. R. de Carvalho, I. G. de la Rosa +3
We use SDSS-DR4 photometric and spectroscopic data out to redshift z~0.1 combined with ROSAT All Sky Survey X-ray data to produce a sample of twenty-five fossil groups (FGs), defin…
Post Common Envelope Binaries from SDSS. V: Four eclipsing white dwarf main sequence binaries
S. Pyrzas, B. T. Gänsicke, T. R. Marsh +7
We identify SDSS011009.09+132616.1, SDSS030308.35+005444.1, SDSS143547.87+373338.5 and SDSS154846.00+405728.8 as four eclipsing white dwarf plus main sequence (WDMS) binaries from…
Star-forming galaxies in SDSS: signs of metallicity evolution
M. A. Lara-Lopez, J. Cepa, A. Bongiovanni +5
Evolution of galaxies through cosmic time has been widely studied at high redshift, but there are a few studies in this field at lower redshifts. However, low-redshifts studies wil…
Identifying nearby field T dwarfs in the UKIDSS Galactic Clusters Survey
N. Lodieu, B. Burningham, N. C. Hambly +1
We present the discovery of two new late-T dwarfs identified in the UKIRT Infrared Deep Sky Survey (UKIDSS) Galactic Clusters Survey (GCS) Data Release 2 (DR2). These T dwarfs are…
A HST/WFPC2 survey of bright young clusters in M31. I. VdB0, a massive star cluster seen at ~= 25 Myr
S. Perina, P. Barmby, M. A. Beasley +12
{Aims.} We introduce our imaging survey of possible young massive globular clusters in M31 performed with the Wide Field and Planetary Camera 2 (WFPC2) on the Hubble Space Telescop…
WINGS-SPE Spectroscopy in the WIde-field Nearby Galaxy-cluster Survey
A. Cava, D. Bettoni, B. M. Poggianti +11
Aims. We present the results from a comprehensive spectroscopic survey of the WINGS (WIde-field Nearby Galaxy-cluster Survey) clusters, a program called WINGS-SPE. The WINGS-SPE sa…
A cool starspot or a second transiting planet in the TrES-1 system?
M. Rabus, R. Alonso, J. A. Belmonte +6
We investigate the origin of a flux increase found during a transit of TrES-1, observed with the HST. This feature in the HST light curve cannot be attributed to noise and is suppo…
The JCMT Nearby Galaxies Legacy Survey I. Star Forming Molecular Gas in Virgo Cluster Spiral Galaxies
C. D. Wilson, B. E. Warren, F. P. Israel +20
We present large-area maps of the CO J=3-2 emission obtained at the James Clerk Maxwell Telescope for four spiral galaxies in the Virgo Cluster. We combine these data with publishe…
The June 2008 flare of Markarian 421 from optical to TeV energies
The Agile Collaboration, Webt Collaboration, Magic Collaboration +2
We present optical, X-ray, high energy ( GeV) and very high energy ( GeV; VHE) observations of the high-frequency peaked blazar Mrk 421 taken betwee…
Characterization of the HD 17156 planetary system
M. Barbieri, R. Alonso, S. Desidera +11
AIMS : To improve the parameters of the HD 17156 system (peculiar due to the eccentric and long orbital period of its transiting planet) and constrain the presence of stellar compa…
