BULGE n AND B/T IN HIGH-MASS GALAXIES: CONSTRAINTS ON THE ORIGIN OF BULGES IN HIERARCHICAL MODELS
- T. Weinzirl, S. Jogee, S. Khochfar, A. Burkert, J. Kormendy
- Physics
- 1 July 2008
We use the bulge Sérsic index n and bulge-to-total mass ratio (B/T) to explore the fundamental question of how bulges form. We perform two-dimensional bulge–disk–bar decomposition on H-band images of…
The Hubble Space Telescope GOODS NICMOS Survey: Overview and the Evolution of Massive Galaxies at 1.5 < z < 3
- C. Conselice, A. Bluck, T. Weinzirl
- Physics
- 6 October 2010
We present the details and early results from a deep near-infrared survey utilizing the NICMOS instrument on the Hubble Space Telescope centred around massive M_* > 10^(11) M_⊙ galaxies at 1.7…
INSIGHTS ON THE FORMATION, EVOLUTION, AND ACTIVITY OF MASSIVE GALAXIES FROM ULTRACOMPACT AND DISKY GALAXIES AT z = 2–3
- T. Weinzirl, S. Jogee, A. Bauer
- Physics
- 13 July 2011
We present our results on the structure and activity of massive galaxies at z = 1–3 using one of the largest (166 with M⋆ ⩾ 5 × 1010 M☉) and most diverse samples of massive galaxies derived from the…
The VIRUS-P Exploration of Nearby Galaxies (VENGA): Spatially Resolved Gas-Phase Metallicity Distributions in Barred and Unbarred Spirals
- K. Kaplan, S. Jogee, R. V. D. Bosch
- Physics
- 18 June 2016
We present a study of the excitation conditions and metallicity of ionized gas (Z_gas) in eight nearby barred and unbarred spiral galaxies from the VIRUS-P Exploration of Nearby Galaxies (VENGA)…
The HST/ACS Coma Cluster Survey. X. Nuclear star clusters in low-mass early-type galaxies: scaling relations
- M. D. Brok, R. Peletier, T. Weinzirl
- Physics
- 16 September 2014
We present scaling relations between structural properties of nuclear star clusters and their host galaxies for a sample of early-type dwarf galaxies observed as part of the Hubble Space Telescope…
THE VIRUS-P EXPLORATION OF NEARBY GALAXIES (VENGA): SURVEY DESIGN, DATA PROCESSING, AND SPECTRAL ANALYSIS METHODS
- G. Blanc, T. Weinzirl, P. Yoachim
- Physics, Geology
- 6 March 2013
We present the survey design, data reduction, and spectral fitting pipeline for the VIRUS-P Exploration of Nearby Galaxies (VENGA). VENGA is an integral field spectroscopic survey, which maps the…
The relationship between star formation rates, local density and stellar mass up to z ~ 3 in the GOODS NICMOS Survey
- R. Gruetzbauch, C. Conselice, S. Jogee
- Physics
- 1 August 2011
We investigate the relation between star formation rates and local galaxy environment for a stellar-mass-selected galaxy sample in the redshift range 1.5 ≤z≤ 3. We use near-infrared imaging from an…
The HST/ACS coma cluster survey – VI. Colour gradients in giant and dwarf early-type galaxies
- M. D. Brok, R. Peletier, T. Weinzirl
- Physics
- 7 March 2011
Using deep, high-spatial resolution imaging from the HST ACS Coma Cluster Treasury Survey, we determine colour profiles of early-type galaxies in the Coma cluster. From 176 galaxies brighter than…

- I. Marinova, S. Jogee, G. V. Kleijn
- Physics
- 20 March 2011
We use high-resolution (∼0.″1) F814W Advanced Camera for Surveys (ACS) images from the Hubble Space Telescope ACS Treasury survey of the Coma cluster at z ∼ 0.02 to study bars in massive disk…
OMEGA – OSIRIS Mapping of Emission-line Galaxies in A901/2: II. Environmental influence on integrated star formation properties and AGN activity
- B. R. D. Pino, A. Arag'on-Salamanca, C. Wolf
- Physics
- 23 January 2017
We present a study of the star formation and AGN activity for galaxies in CP 15051 the Abell 901/2 multicluster system at z ∼ 0.167 as part of the OSIRIS Mapping of Emission-line Galaxies in A901/2…
