Search for Early Gamma-ray Production in Supernovae Located in a Dense Circumstellar Medium with the Fermi LAT

M. Ackermann, I. Arcavi, L. Baldini +108

Supernovae (SNe) exploding in a dense circumstellar medium (CSM) are hypothesized to accelerate cosmic rays in collisionless shocks and emit GeV gamma rays and TeV neutrinos on a t…

Probing the role of the galactic environment in the formation of stellar clusters; using M83 as a test bench

Angela Adamo, Diederik Kruijssen, Nate Bastian +2

We present a study of the M83 cluster population, covering the disc of the galaxy between radii of 0.45 and 4.5 kpc. We aim to probe the properties of the cluster population as a f…

Hierarchical Star Formation across the ring galaxy NGC 6503

Dimitrios A. Gouliermis, David Thilker, Bruce G. Elmegreen +25

We present a detailed clustering analysis of the young stellar population across the star-forming ring galaxy NGC 6503, based on the deep HST photometry obtained with the Legacy Ex…

Sizes and Shapes of Young Star Cluster Light Profiles in M83

Jenna E. Ryon, Nate Bastian, Angela Adamo +6

We measure the radii and two-dimensional light profiles of a large sample of young, massive star clusters in M83 using archival HST/WFC3 imaging of seven adjacent fields. We use GA…

Preflight performance studies of the PoGOLite hard X-ray polarimeter

M. Chauvin, M. Jackson, T. Kawano +6

Polarimetric studies of astrophysical sources can make important contributions to resolve the geometry of the emitting region and determine the photon emission mechanism. PoGOLite…

Lyman alpha Emitting Galaxies in the Nearby Universe

Matthew Hayes

The Lya emission line of HI is intrinsically the brightest feature in the spectrum of astrophysical nebulae, making it a very attractive observational tool with which to survey gal…
