The Lyman Reference Sample XIV: Lyman imaging of 45 low redshift star-forming galaxies and inferences on global emission
Jens Melinder, Göran Östlin, Matthew Hayes +18
We present Ly imaging of 45 low redshift star-forming galaxies observed with the Hubble Space Telescope. The galaxies have been selected to have moderate to high star formation…
The Lyman Alpha Reference Sample IX: Revelations from deep surface photometry
Genoveva Micheva, Göran Östlin, Erik Zackrisson +7
The Lyman Alpha Reference Sample (LARS) of 14 star-forming galaxies offers a wealth of insight into the workings of these local analogs to high-redshift star-forming galaxies. The…
The Lyman alpha Reference Sample VI: Lyman alpha escape from the edge-on disk galaxy Mrk1486
Florent Duval, Göran Östlin, Matthew Hayes +16
While numerical simulations suggest that the strength of the Lyman alpha (Lya) line of star-forming disk galaxies strongly depends on the inclination at which they are observed (i.…
Limits on Lyman Continuum escape from z=2.2 H-alpha emitting galaxies
A. Sandberg, G. Östlin, J. Melinder +2
The leakage of Lyman continuum photons from star forming galaxies is an elusive parameter. When observed, it provides a wealth of information on star formation in galaxies and the…
The Lyman Alpha Reference Sample: V. The impact of neutral ISM kinematics and geometry on Lyman Alpha escape
Thøger E. Rivera-Thorsen, Matthew Hayes, Göran Östlin +15
We present high-resolution far-UV spectroscopy of the 14 galaxies of the Lyman Alpha Reference Sample; a sample of strongly star-forming galaxies at low redshifts ($0.028 < z < 0.1…
The Lyman alpha reference sample: IV. Morphology at low and high redshift
L. Guaita, J. Melinder, M. Hayes +3
We measured the sizes and morphological parameters of LARS galaxies in the continuum, Lya, and Ha images. We studied morphology by using the Gini coefficient vs M20 and asymmetry v…
Trident: A three-pronged galaxy survey. I. Lyman alpha emitting galaxies at z~2 in GOODS North
A. Sandberg, L. Guaita, G. Östlin +2
Context. Lyman alpha emitting galaxies (LAEs) are used to probe the distant universe and are therefore important for galaxy evolution studies and for providing clues to the nature…
The Lyman-alpha Reference Sample: I. Survey outline and first results for Markarian 259
Göran Östlin, Matthew Hayes, Florent Duval +19
The Lyman-alpha reference sample (LARS) is a program with the Hubble Space Telescope (HST) that provides a sample of local universe laboratory galaxies in which to study the astrop…
The Lyman Alpha Reference Sample: III. Properties of the Neutral ISM from GBT and VLA Observations
Stephen A. Pardy, John M. Cannon, Göran Östlin +16
We present new H I imaging and spectroscopy of the 14 UV-selected star-forming galaxies in the Lyman Alpha Reference Sample (LARS), aimed for a detailed study of the processes gove…
GRB 120422A/SN 2012bz: Bridging the Gap between Low- And High-Luminosity GRBs
S. Schulze, D. Malesani, A. Cucchiara +62
At low redshift, a handful of gamma-ray bursts (GRBs) have been discovered with peak luminosities () substantially lower than the average…
The Lyman alpha Reference Sample: II. HST imaging results, integrated properties and trends
Matthew Hayes, Göran Östlin, Florent Duval +16
We report upon new results regarding the Lya output of galaxies, derived from the Lyman alpha Reference Sample (LARS), focusing on Hubble Space Telescope imaging. For 14 galaxies w…
Neutral gas in Lyman-alpha emitting galaxies Haro 11 and ESO 338-IG04 measured through sodium absorption
A. Sandberg, G. Östlin, M. Hayes +4
Context. The Lyman alpha emission line of galaxies is an important tool for finding galaxies at high redshift, and thus probe the structure of the early universe. However, the reso…
The Lyman alpha Reference Sample: Extended Lyman alpha Halos Produced at Low Dust Content
Matthew Hayes, Göran Östlin, Daniel Schaerer +14
We report on new imaging observations of the Lyman alpha emission line (Lya), performed with the Hubble Space Telescope, that comprise the backbone of the Lyman alpha Reference Sam…
Hunting for dark halo substructure using submilliarcsecond-scale observations of macrolensed radio jets
Erik Zackrisson, Saghar Asadi, Kaj Wiik +8
Dark halo substructure may reveal itself through secondary, small-scale gravitational lensing effects on light sources that are macrolensed by a foreground galaxy. Here, we explore…
