Virgo Cluster and field dwarf ellipticals in 3D - II. Internal dynamics points to tidal harassment?
Agnieszka Ryś, Glenn van de Ven, Jesús Falcón-Barroso
We present the dynamical analysis of a sample of 12 dwarf elliptical (dE) galaxies for which we have obtained SAURON large-scale two-dimensional spectroscopic data. We construct Je…
A characteristic oxygen abundance gradient in galaxy disks unveiled with CALIFA
S. F. Sanchez, F. F. Rosales-Ortega, J. Iglesias-Paramo +35
We present the largest and most homogeneous catalog of HII regions and associations compiled so far. The catalog comprises more than 7000 ionized regions, extracted from 306 galaxi…
The effects of spatial resolution on Integral Field Spectrograph surveys at different redshifts. The CALIFA perspective
D. Mast, F. F. Rosales-Ortega, S. F. Sanchez +27
Over the past decade, 3D optical spectroscopy has become the preferred tool for understanding the properties of galaxies and is now increasingly used to carry out galaxy surveys. L…
The central mass and mass-to-light profile of the Galactic globular cluster M15
Mark den Brok, Glenn van de Ven, Remco van den Bosch +1
We analyze line-of-sight velocity and proper motion data of stars in the Galactic globular cluster M15 using a new method to fit dynamical models to discrete kinematic data. Our fi…
Bar pattern speed and position of the circumnuclear ring in NGC 1097
N. Piñol-Ferrer, K. Fathi, C. Carignan +4
We present the first galactic-scale model of the gas dynamics of the prototype barred Seyfert 1 galaxy NGC1097. We use large scale FaNTOmM Fabry-Perot interferometric data covering…
Supermassive Black Holes and Their Host Galaxies - II. The correlation with near-infrared luminosity revisited
Ronald Läsker, Laura Ferrarese, Glenn van de Ven +1
We present an investigation of the scaling relations between Supermassive Black Hole (SMBH) masses (Mbh), and their host galaxies' K-band bulge (Lbul) and total (Ltot) luminosities…
Supermassive Black Holes and Their Host Galaxies - I. Bulge luminosities from dedicated near-infrared data
Ronald Läsker, Laura Ferrarese, Glenn van de Ven
In an effort to secure, refine and supplement the relation between central Supermassive Black Hole masses (Mbh), and the bulge luminosities of their host galaxies, (Lbul), we obtai…
The ATLAS project - XXV: Two-dimensional kinematic analysis of simulated galaxies and the cosmological origin of fast and slow rotators
T. Naab, L. Oser, E. Emsellem +26
We present a detailed two-dimensional stellar dynamical analysis of a sample of 44 cosmological hydrodynamical simulations of individual central galaxies and their satellites. Kine…
The star formation history of CALIFA galaxies: Radial structures
R. M. González Delgado, E. Pérez, R. Cid Fernandes +24
We study the radial structure of the stellar mass surface density () and stellar population age as a function of the total stellar mass and morphology for a sample of 107 galaxi…
The nature of LINER galaxies: Ubiquitous hot old stars and rare accreting black holes
R. Singh, G. van de Ven, K. Jahnke +19
Galaxies, which often contain ionised gas, sometimes also exhibit a so-called low-ionisation nuclear emission line region (LINER). For 30 years this was attributed to a central mas…
Discovery of a Quadruple Lens in CANDELS with a Record Lens Redshift z=1.53
A. van der Wel, G. van de Ven, M. Maseda +10
Using spectroscopy from the Large Binocular Telescope and imaging from the Hubble Space Telescope we discovered the first strong galaxy lens at z(lens)>1. The lens has a secure pho…
Discrete dynamical modelling of omega Centauri
Laura L. Watkins, Glenn van de Ven, Mark den Brok +1
We present a new framework for modelling discrete kinematic data. Current techniques typically involve binning. Our approach works directly with the discrete data and uses maximum-…
An Integral View of Balmer-dominated Shocks in Supernova Remnants
Sladjana Nikolić, Glenn van de Ven, Kevin Heng +5
We present integral-field spectroscopic observations with the VIMOS-IFU at the VLT of fast (2000-3000 km/s) Balmer-dominated shocks surrounding the northwestern rim of the remnant…
The O3N2 and N2 abundance indicators revisited: improved calibrations based on CALIFA and Te-based literature data
R. A. Marino, F. F. Rosales-Ortega, S. F. Sánchez +31
The use of IFS is since recently allowing to measure the emission line fluxes of an increasingly large number of star-forming galaxies both locally and at high redshift. The main g…
Nebular emission and the Lyman continuum photon escape fraction in CALIFA early-type galaxies
P. Papaderos, J. M. Gomes, J. M. Vilchez +21
We use deep integral field spectroscopy data from the CALIFA survey to study the warm interstellar medium (WIM) of 32 nearby early-type galaxies (ETGs). We propose a tentative subd…
