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…
A variation of the fraction of stars that form in bound clusters within M83
Esteban Silva-Villa, Angela Adamo, Nate Bastian
Recent observations, as well as theoretical studies, have suggested that stellar cluster formation may depend on local and global environmental properties. In particular, the fract…
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…
The Snapshot Hubble U-Band Cluster Survey (SHUCS). I. Survey Description and First Application to the Mixed Star Cluster Population of NGC 4041
I. S. Konstantopoulos, L. J. Smith, A. Adamo +9
We present the Snapshot Hubble U-band Cluster Survey (SHUCS), a project aimed at characterizing the star cluster populations of ten nearby galaxies (d<23 Mpc, half within 12 Mpc) t…
High resolution study of the cluster complexes in a lensed spiral at redshift ~1.5; constraints on the bulge formation and disk evolution
Angela Adamo, Goeran Ostlin, Nate Bastian +3
We analyse the clump population of the spiral galaxy Sp 1149 at redshift 1.5. Located behind the galaxy cluster MACS J1149.5+2223, Sp 1149 has been significantly magnified allowing…
Age Dating Stellar Populations in the Near Infrared: An absolute age indicator from the presence/absence of red supergiants
J. Zachary Gazak, N. Bastian, R. P. Kudritzki +4
The determination of age is a critical component in the study of a population of stellar clusters. In this letter we present a new absolute age indicator for young massive star clu…
The Snapshot Hubble U-band Cluster Survey; A cluster complex in NGC 2146
Angela Adamo, Linda J. Smith
We present the Snapshot Hubble U-band Cluster Survey (SHUCS), an ongoing deep U-band imaging survey of nearby star-forming galaxies. Thanks to the information provided by the U ban…
Stellar Clusters in M83: Formation, evolution, disruption and the influence of environment
N. Bastian, A. Adamo, M. Gieles +6
We study the stellar cluster population in two adjacent fields in the nearby, face-on spiral galaxy, M83, using WFC3/HST imaging. The clusters are selected through visual inspectio…
Probing cluster formation under extreme conditions: massive star clusters in blue compact galaxies
Angela Adamo, Goeran Ostlin, Erik Zackrisson
The numerous and massive young star clusters in blue compact galaxies (BCGs) are used to investigate the properties of their hosts. We test whether BCGs follow claimed relations be…
Probing the near-IR flux excess in young star clusters
Angela Adamo, Goeran Ostlin, Erik Zackrisson
We report the results of a recent study of young star clusters (YSCs) in luminous blue compact galaxies (BCGs). The age distributions of the YSCs suggest that the starburst episode…
Star cluster formation and evolution in Mrk 930: properties of a metal-poor starburst
A. Adamo, G. Ostlin, E. Zackrisson +4
We present a HST multiband analysis of the large population of star clusters in the blue compact galaxy (BCG) Mrk 930. We have reconstructed the spectral energy distributions of th…
The Massive Star Clusters in the Dwarf Merger ESO 185-IG13: is the Red Excess Ubiquitous in Starbursts?
Angela Adamo, Goeran Ostlin, Erik Zackrisson +1
We have investigated the starburst properties of the luminous blue compact galaxy ESO 185-IG13. The galaxy has been imaged with the high resolution cameras onboard to the Hubble Sp…
The Extremely Young Star Cluster Population In Haro 11
Angela Adamo, Göran Östlin, Erik Zackrisson +1
We have performed a deep multi-band photometric analysis of the star cluster population of Haro 11. This starburst galaxy (log L_FUV = 10.3 L_sun) is considered a nearby analogue o…
Tracing the star formation history of three Blue Compact galaxies through the analysis of their star clusters
Angela Adamo, Göran Östlin, Erik Zackrisson +1
We present preliminary results from a study of the compact star cluster populations in three local luminous blue compact galaxies: ESO 185-IG 013, ESO 350-IG 038 (a.k.a. Haro 11),…
