Extragalactic large-scale structures in the northern Zone of Avoidance
M Ramatsoku, R C Kraan-Korteweg, A C Schröder +1
We used the Nançay Radio Telescope (NRT) to measure the 21 cm line emission of near-infrared bright galaxies in the northern Zone of Avoidance (ZoA) without previous redshift deter…
On the self-regulation of intense star-formation in galaxies at z=1-3
M. D. Lehnert, L. Le Tiran, N. P. H. Nesvadba +3
(abridged) We have analyzed the properties of the rest-frame optical emission lines of a sample of 53 intensely star forming galaxies at z=1.3 to 2.7 observed with SINFONI on the E…
The Next Generation Virgo Cluster Survey. IV. NGC 4216: A Bombarded Spiral in the Virgo Cluster
Sanjaya Paudel, Pierre-Alain Duc, Patrick Cote +16
We present an investigation into the origins of a series of interlaced narrow filamentary stellar structures, loops and plumes in the vicinity of the Virgo Cluster, edge-on spiral…
Simultaneous multi-band detection of Low Surface Brightness galaxies with Markovian modelling
B. Vollmer, B. Perret, M. Petremand +7
We present an algorithm for the detection of Low Surface Brightness (LSB) galaxies in images, called MARSIAA (MARkovian Software for Image Analysis in Astronomy), which is based on…
The GALEX Ultraviolet Virgo Cluster Survey (GUViCS). II. Constraints on star formation in ram-pressure stripped gas
S. Boissier, A. Boselli, P. -A. Duc +10
Context: Several galaxies in the Virgo cluster are known to have large HI gas tails related to a recent ram-pressure stripping event. The Virgo cluster has been extensively observe…
Minor mergers and their impact on the kinematics of old and young stellar populations in disk galaxies
Y. Qu, P. Di Matteo, M. D. Lehnert +2
By means of N-body simulations we investigate the impact of minor mergers on the angular momentum and dynamical properties of the merger remnant. Our simulations cover a range of i…
The Average Optical Spectra of Intense Starbursts at z~2: Outflows and the Pressurization of the ISM
L. Le Tiran, M. D. Lehnert, W. van Driel +2
An important property of star-forming galaxies at z~1-2 is the high local star-formation intensities they maintain over tens of kiloparsecs at levels that are only observed in the…
The Na D profiles of nearby low-power radio sources: Jets powering outflows
M. D. Lehnert, C. Tasse, N. P. H. Nesvadba +2
(abridged) We have analyzed the properties of the Na D doublet lines in a large sample of 691 radio galaxies using the Sloan Digital Sky Survey (SDSS). These radio galaxies are res…
Can Cosmological Accretion be Observed in H-alpha at z~2?
Loïc Le Tiran, Matthew D. Lehnert, Paola Di Matteo +2
In previous studies, it has been shown that the large line widths observed in high surface brightness H-alpha emitters at low and high redshifts are likely due to the mechanical en…
The GALEX Ultraviolet Virgo Cluster Survey (GUViCS). I: The UV luminosity function of the central 12 sq.deg
A. Boselli, S. Boissier, S. Heinis +50
The GALEX Ultraviolet Virgo Cluster Survey (GUViCS) is a complete blind survey of the Virgo cluster covering about 40 sq. deg. in the far UV (FUV, lambda_eff=1539A, Delta-lambda=44…
The formation of a thick disk through the heating of a thin disk: Agreement with orbital eccentricities of stars in the solar neighborhood
P. Di Matteo, M. D. Lehnert, Y. Qu +1
We study the distribution of orbital eccentricities of stars in thick disks generated by the heating of a pre-existing thin stellar disk through a minor merger (mass ratio 1:10), u…
HI line observations of 2MASS galaxies in the Zone of Avoidance
W. van Driel, S. E. Schneider, R. C. Kraan-Korteweg +1
A pilot survey has been made to obtain 21cm HI emission line profiles for 197 objects in the Zone of Avoidance (ZoA) that were classified as galaxies in the 2MASS all-sky near-infr…
Physical conditions in the ISM of intensely star-forming galaxies at redshift~2
M. D. Lehnert, N. P. H. Nesvadba, L. Le Tiran +5
We analyze the physical conditions in the interstellar gas of 11 actively star-forming galaxies at z~2, based on integral-field spectroscopy from the ESO-VLT and HST/NICMOS imaging…
