Star formation and mass assembly in high-redshift galaxies
- P. Santini, A. Fontana, I. Vergata
- Physics

Aims. The goal of this work is to infer the star formation properties and the mass assembly process of high redshift (0.3 ≤ z 0.3, the star formation rate is correlated well with stellar mass, and…
Detection of high Lyman continuum leakage from four low-redshift compact star-forming galaxies
- Y. Izotov, D. Schaerer, Czech Republic
- Physics
- 17 May 2016
Following our first detection reported in Izotov et al. (2016), we present the detection of Lyman continuum (LyC) radiation of four other compact star-forming galaxies observed with the Cosmic…
Substructure revealed by RR Lyraes in SDSS Stripe 82
- L. Watkins, N. Evans, Macquarrie
- Physics
- 2 June 2009
We present an analysis of the substructure revealed by RR Lyraes in Sloan Digital Sky Survey Stripe 82, which covers 2°5 in declination on the celestial equator over the right ascension range α = 20…
The Luminosity Function of the Milky Way Satellites
- Sergey E. Koposov, V. Belokurov, Russia.
- Physics
- 19 June 2007
We quantify the detectability of stellar Milky Way satellites in the Sloan Digital Sky Survey (SDSS) Data Release 5. We show that the effective search volumes for the recently discovered SDSS…
CONSTRAINING THE MILKY WAY POTENTIAL WITH A SIX-DIMENSIONAL PHASE-SPACE MAP OF THE GD-1 STELLAR STREAM
- Sergey E. Koposov, H. Rix, Usa
- Physics, Geology
- 7 July 2009
The narrow GD-1 stream of stars, spanning 60° on the sky at a distance of ∼10 kpc from the Sun and ∼15 kpc from the Galactic center, is presumed to be debris from a tidally disrupted star cluster…
THE MAGELLANIC MOPRA ASSESSMENT (MAGMA). I. THE MOLECULAR CLOUD POPULATION OF THE LARGE MAGELLANIC CLOUD
We present the properties of an extensive sample of molecular clouds in the Large Magellanic Cloud (LMC) mapped at 11 pc resolution in the CO(1–0) line. Targets were chosen based on a limiting CO…
Protoclusters associated with z > 2 radio galaxies - I. Characteristics of high redshift protoclusters
- B. Venemans, H. Rottgering, U. Davis
- Physics
- 18 October 2006
We present the results of a large program conducted with the Very Large Telescope and augmented by observations with the Keck telescope to search for forming clusters of galaxies near powerful radio…
Kinematics of SDSS subdwarfs: structure and substructure of the Milky Way halo
We construct a new sample of ∼ 1700 solar neighbourhood halo subdwarfs from the Sloan Digital Sky Survey (SDSS), selected using a reduced proper-motion diagram. Radial velocities come from the SDSS…
The 3D structure of the Virgo cluster from H-band Fundamental Plane and Tully—Fisher distance determinations
- G. Gavazzi, A. Boselli, Heidelberg
- Physics
- 15 December 1998
We undertook a surface photometry survey of 200 galaxies in the Virgo cluster (complete to B<14.0 mag) carried out in the near-infrared (NIR) H band. Combining velocity dispersion measurements from…
Nebular abundances of nearby southern dwarf galaxies
The results of optical spectroscopy of H II regions in a sample of southern dwarf irregulars consisting of five dwarf galaxies in the Centaurus A group, four dwarfs in the Sculptor group, and eight…
