Star-formation in the HI bridge between M81 and M82
Duilia F. de Mello, L. J. Smith, E. Sabbi +3
We present multi-wavelength observations of stellar features in the HI tidal bridge connecting M81 and M82 in the region called Arp's Loop. We identify eight young star-forming reg…
Star Formation in NGC 5194 (M51a). II. The Spatially-Resolved Star Formation Law
Robert C. Kennicutt, Daniela Calzetti, Fabian Walter +20
We have studied the relationship between the star formation rate (SFR) surface density and gas surface density in the spiral galaxy M51a (NGC 5194), using multi-wavelength data obt…
New Constraints on the Lyman Continuum Escape Fraction at z~1.3
Brian Siana, Harry I. Teplitz, James Colbert +8
We examine deep far-ultraviolet (1600 Angstrom) imaging of the Hubble Deep Field-North (HDFN) and the Hubble Ultra Deep Field (HUDF) to search for leaking Lyman continuum radiation…
Near Ultraviolet sources in the Great Observatories Origins Deep Survey Fields
Duilia de Mello, T. Dahlen, J. P. Gardner +1
We present an Ultraviolet (UV) selected sample of 268 objects in the two fields of the Great Observatories Origins Deep Survey (GOODS). We used the parallel observations taken with…
Faint U-Band Dropouts in the WFPC2 Parallels of the Hubble Ultra Deep Field
Yogesh Wadadekar, Stefano Casertano, Duilia de Mello
We combine data from the extremely deep Hubble Space Telescope (F300W) image obtained using WFPC2 as part of the parallel observations of the Hubble Ultra Deep Field campaign,…
Star--forming galaxies at intermediate redshifts: morphology, ages and sizes
Duilia. F. de Mello, Y. Wadadekar, T. Dahlen +2
We present the analysis of the deepest near-UV image obtained with HST using the WFPC2(F300W) as part of the parallel observations of the Ultra Deep Field campaign. The U-band 10si…
