The VIMOS VLT Deep Survey. Public release of 1599 redshifts to IAB≤24 across the Chandra Deep Field South
Bondi, M.; Maccagni, D.; Ilbert, O. +47 more
This paper presents the VIMOS VLT Deep Survey around the Chandra Deep Field South (CDFS). We have measured 1599 new redshifts with VIMOS on the European Observatory Very Large Telescope - UT3, in an area 21 × 21.6 arcmin2, including 784 redshifts in the Hubble Space Telescope - Advanced Camera for Surveys GOODS area. 30% of all objects …
UV star-formation rates of GRB host galaxies
Christensen, L.; Gorosabel, J.; Hjorth, J.
We study a magnitude-limited sample of 10 gamma-ray burst (GRB) host galaxies with known spectroscopic redshifts (0.43 < z < 2.04). From an analysis of the spectral energy distributions (SEDs), based on published broad-band optical and near-infrared photometry, we derive photometric redshifts, galaxy types, ages of the dominant stellar popul…
2MASS NIR photometry for 693 candidate globular clusters in M 31 and the Revised Bologna Catalogue
Bellazzini, M.; Galleti, S.; Federici, L. +2 more
We have identified in the 2MASS database 693 known and candidate globular clusters in M 31. The 2MASS J, H, K magnitudes of these objects have been transformed to the same homogeneous photometric system of existing near infrared photometry of M 31 globulars, finally yielding J, H, K integrated photometry for 279 confirmed M 31 clusters, 406 unconf…
The host of GRB 030323 at z=3.372: A very high column density DLA system with a low metallicity
Pian, E.; Palazzi, E.; Kouveliotou, C. +29 more
We present photometry and spectroscopy of the afterglow of GRB 030323. VLT spectra of the afterglow show damped Lyα (DLA) absorption and low- and high-ionization lines at a redshift z=3.3718±0.0005. The inferred neutral hydrogen column density, log N(H I)=21.90±0.07, is larger than any (GRB- or QSO-) DLA H I column density inferred directly from L…
The structure and environment of young stellar clusters in spiral galaxies
Larsen, S. S.
A search for stellar clusters has been carried out in 18 nearby spiral galaxies, using archive images from the Wide Field Planetary Camera 2 on board the Hubble Space Telescope. All of the galaxies have previously been imaged from the ground in UBVI. A catalogue of structural parameters, photometry and comments based on visual inspection of the cl…
Double-barred galaxies. I. A catalog of barred galaxies with stellar secondary bars and inner disks
Erwin, Peter
I present a catalog of 67 barred galaxies which contain distinct, elliptical stellar structures inside their bars. Fifty of these are double-barred galaxies: a small-scale, inner or secondary bar is embedded within a large-scale, outer or primary bar. I provide homogenized measurements of the sizes, ellipticities, and orientations of both inner an…
The dynamical mass of the young cluster W3 in NGC 7252. Heavy-weight globular cluster or ultra compact dwarf galaxy?
Saglia, R. P.; Bastian, N.; Maraston, C. +3 more
We have determined the dynamical mass of the most luminous stellar cluster known to date, i.e. object W3 in the merger remnant galaxy NGC 7252. The dynamical mass is estimated from the velocity dispersion measured with the high-resolution spectrograph UVES on VLT. Our result is the astonishingly high velocity dispersion of σ=45 ± 5 km s-1
The nature of the Galactic Center source IRS 13 revealed by high spatial resolution in the infrared
Rigaut, F.; Paumard, T.; Stolovy, S. R. +1 more
High spatial resolution observations in the 1 to 3.5 µm/ region of the Galactic Center source known historically as
Detection of Lyman-α emission from a DLA galaxy: Possible implications for a luminosity-metallicity relation at z = 2-3
Fynbo, J. P. U.; Fall, S. M.; Møller, P.
In an ongoing programme to identify a sample of high z DLA galaxies we have found the long sought for case of a Lyα emitter seen in the centre of a broad DLA trough. This is the predicted ``textbook case'' of an intervening DLA galaxy if DLA galaxies are small, but would not be expected if intervening high redshift DLA galaxies have large gaseous …
Contribution of the disk emission to the broad emission lines in AGNs: Two-component model
Bon, E.; Popović, L. Č.; Ilić, D. +1 more
We present an investigation of the structure of the emission line region in a sample of 12 single-peaked Active Galactic Nuclei (AGNs). Using the high resolution Hβ and Hα line profiles observed with the Isaac Newton Telescope (La Palma) we study the substructure in the lines (such as shoulders or bumps) which can indicate a disk or disk-like emis…
