Mid-infrared spectral evidence for a luminous dust enshrouded source in Arp220
H. W. W. Spoon, A. F. M. Moorwood, D. Lutz +3
We have re-analyzed the 6-12 micron ISO spectrum of the ultra-luminous infrared galaxy Arp220 with the conclusion that it is not consistent with that of a scaled up version of a ty…
ISO spectroscopy of star formation and active nuclei in the luminous infrared galaxy NGC 6240
D. Lutz, E. Sturm, R. Genzel +4
We present Infrared Space Observatory mid- and far-infrared spectroscopy of the merging galaxy NGC 6240, an object presenting many aspects of importance for the role of star format…
The Rest-Frame Optical Luminosity Density, Color, and Stellar Mass Density of the Universe from z=0 to z=3
Gregory Rudnick, Hans-Walter Rix, Marijn Franx +11
We present the evolution of the rest-frame optical luminosity density, of the integrated rest-frame optical color, and of the stellar mass density for a sample of Ks-band selected…
The Luminosity-Size and Mass-Size Relations of Galaxies out to z~3
Ignacio Trujillo, Gregory Rudnick, Hans-Walter Rix +11
The luminosity-size and stellar mass-size distributions of galaxies out to z~3 is presented. We use very deep near-infrared images of the Hubble Deep Field South in the J_s, H, and…
Large disk-like galaxies at high redshift
I. Labbe, G. Rudnick, M. Franx +11
Using deep near-infrared imaging of the Hubble Deep Field South with ISAAC on the Very Large Telescope we find 6 large disk-like galaxies at redshifts z = 1.4-3.0. The galaxies, se…
H-alpha Spectroscopy of Galaxies at z>2: Kinematics and Star Formation
Dawn K. Erb, Alice E. Shapley, Charles C. Steidel +5
We present near-infrared spectroscopy of H-alpha emission lines in a sample of 16 star-forming galaxies at redshifts 2.0<z<2.6. Our targets are drawn from a large sample of galaxie…
Spectroscopic Confirmation of a Substantial Population of Luminous Red Galaxies at Redshifts z>2
Pieter G. van Dokkum, Natascha M. Forster Schreiber, Marijn Franx +10
We confirm spectroscopically the existence of a population of galaxies at z>~2 with rest-frame optical colors similar to normal nearby galaxies. The galaxies were identified by the…
Detection of strong clustering of red K-selected galaxies at 2<z_phot<4 in the Hubble Deep Field South
E. Daddi, H. Rottgering, I. Labbe +6
The clustering properties of faint K<24 galaxies are measured in ultradeep J, H and K near-IR images of the Hubble Deep Field South (HDF-S), obtained with ISAAC at the VLT. A relat…
Detection of strongly processed ice in the central starburst of NGC4945
H. W. W. Spoon, A. F. M. Moorwood, K. M. Pontoppidan +4
The composition of ice grains provides an important tool for the study of the molecular environment of star forming regions. Using ISAAC at the VLT to obtain spectra around 4.65 mi…
