MUSE observations of the counter-rotating nuclear ring in NGC 7742
Thomas P. K. Martinsson, Marc Sarzi, Johan H. Knapen +4
We present results from MUSE observations of the nearly face-on disk galaxy NGC 7742. This galaxy hosts a spectacular nuclear ring of enhanced star formation, which is unusual in t…
Inferring gas-phase metallicity gradients of galaxies at the seeing limit: A forward modelling approach
David Carton, Jarle Brinchmann, Maryam Shirazi +7
We present a method to recover the gas-phase metallicity gradients from integral field spectroscopic (IFS) observations of barely resolved galaxies. We take a forward modelling app…
An Empirical Relation Between The Large-Scale Magnetic Field And The Dynamical Mass In Galaxies
F. S. Tabatabaei, T. P. K. Martinsson, J. H. Knapen +3
The origin and evolution of cosmic magnetic fields as well as the influence of the magnetic fields on the evolution of galaxies are unknown. Though not without challenges, the dyna…
Deep MUSE observations in the HDFS. Morpho-kinematics of distant star-forming galaxies down to M
T. Contini, B. Epinat, N. Bouché +20
(Abridged) We make use of the deepest VLT/MUSE observations performed so far on the Hubble Deep Field South (HDFS) to characterize the low-mass (< M) galaxy popula…
The DiskMass Survey. X. Radio synthesis imaging of spiral galaxies
Thomas P. K. Martinsson, Marc A. W. Verheijen, Matthew A. Bershady +3
We present results from 21 cm radio synthesis imaging of 28 spiral galaxies from the DiskMass Survey obtained with the VLA, WSRT, and GMRT facilities. We detail the observations an…
A MUSE map of the central Orion Nebula (M 42)
Peter M. Weilbacher, Ana Monreal-Ibero, Wolfram Kollatschny +15
We present a new integral-field spectroscopic dataset of the central part of the Orion Nebula (M 42), observed with the MUSE instrument at the ESO VLT. We reduced the data with the…
Unveiling the counter-rotating nature of the kinematically distinct core in NGC5813 with MUSE
Davor Krajnovic, Peter M. Weilbacher, Tanya Urrutia +9
MUSE observations of NGC5813 reveal a complex structure in the velocity dispersion map, previously hinted by SAURON observations. The structure is reminiscent of velocity dispersio…
A Fundamental Plane of Spiral Structure in Disk Galaxies
Benjamin L. Davis, Daniel Kennefick, Julia Kennefick +7
Spiral structure is the most distinctive feature of disk galaxies and yet debate persists about which theory of spiral structure is the correct one. Many versions of the density wa…
The MUSE 3D view of the Hubble Deep Field South
R. Bacon, J. Brinchmann, J. Richard +35
We observed the Hubble Deep Field South with the new panoramic integral field spectrograph MUSE that we built and just commissioned at the VLT. The data cube resulting from 27 hour…
The Link Between Light and Mass in Late-type Spiral Galaxy Disks
Robert A. Swaters, Matthew A. Bershady, Thomas P. K. Martinsson +3
We present the correlation between the extrapolated central disk surface brightness (mu) and extrapolated central surface mass density (Sigma) for galaxies in the DiskMass sample.…
MUSE observations of the lensing cluster SMACSJ2031.8-4036: new constraints on the mass distribution in the cluster core
J. Richard, V. Patricio, J. Martinez +10
We present new observations of the lensing cluster SMACSJ2031.8-4036 obtained with the MUSE integral field spectrograph as part of its commissioning on the Very Large Telescope. By…
The DiskMass Survey. VIII. On the Relationship Between Disk Stability and Star Formation
Kyle B. Westfall, David R. Andersen, Matthew A. Bershady +3
We study the relationship between the stability level of late-type galaxy disks and their star-formation activity using integral-field gaseous and stellar kinematic data. Specifica…
The Stability of Galaxy Disks
Kyle B. Westfall, David R. Andersen, Matthew A. Bershady +3
We calculate the stellar surface mass density (Sigma_*) and two-component (gas+stars) disk stability (Q_RW) for 25 late-type galaxies from the DiskMass Survey. These calculations a…
The DiskMass Survey. VII. The distribution of luminous and dark matter in spiral galaxies
Thomas P. K. Martinsson, Marc A. W. Verheijen, Kyle B. Westfall +3
We present dynamically-determined rotation-curve mass decompositions of 30 spiral galaxies, which were carried out to test the maximum-disk hypothesis and to quantify properties of…
The DiskMass Survey. VI. Gas and stellar kinematics in spiral galaxies from PPak integral-field spectroscopy
Thomas P. K. Martinsson, Marc A. W. Verheijen, Kyle B. Westfall +4
We present ionized-gas (OIII) and stellar kinematics (velocities and velocity dispersions) for 30 nearly face-on spiral galaxies out to as much as three disk scale lengths (h_R). T…
Galaxy Disks are Submaximal
Matthew A. Bershady, Thomas P. K. Martinsson, Marc A. W. Verheijen +3
We measure the contribution of galaxy disks to the overall gravitational potential of 30 nearly face-on intermediate-to-late-type spirals from the DiskMass Survey. The central vert…
The DiskMass Survey. IV. The Dark-Matter-Dominated Galaxy UGC 463
Kyle B. Westfall, Matthew A. Bershady, Marc A. W. Verheijen +4
We present a detailed and unique mass budget for the high-surface-brightness galaxy UGC 463, showing it is dominated by dark matter (DM) at radii beyond one scale length (h_R) and…
The DiskMass Survey. II. Error Budget
Matthew A. Bershady, Marc A. W. Verheijen, Kyle B. Westfall +3
We present a performance analysis of the DiskMass Survey. The survey uses collisionless tracers in the form of disk stars to measure the surface-density of spiral disks, to provide…
The DiskMass Survey. I. Overview
Matthew A. Bershady, Marc A. W. Verheijen, Rob A. Swaters +3
We present a survey of the mass surface-density of spiral disks, motivated by outstanding uncertainties in rotation-curve decompositions. Our method exploits integral-field spectro…
