Galactic H2CO Densitometry I: Pilot survey of Ultracompact HII regions and methodology
Adam Ginsburg, Jeremy Darling, Cara Battersby +2
We present a pilot survey of 21 lines of sight towards UCHII regions in the H2CO 1-1 (6cm) and 2-2 (2cm) transitions, using the H2CO centimeter lines as a molecular gas densitomete…
Star-forming Region Sh 2-233IR I. Deep NIR Observations toward the Embedded Stellar Clusters
Chi-Hung Yan, Y. C. Minh, Shiang-Yu Wang +2
We observed the Sh 2-233IR (S233IR) region with better sensitivity in near-infrared than previous studies for this region. By applying statistical subtraction of the back- ground s…
X-ray illumination of the ejecta of Supernova 1987A
J. Larsson, C. Fransson, G. Östlin +25
We present the late-time optical light curve of the ejecta of SN 1987A measured from HST imaging observations spanning the past 17 years. We find that the flux from the ejecta decl…
Morphological evolution of galaxies from ultradeep HST WFC3 imaging: the Hubble sequence at z~2
Daniel Szomoru, Marijn Franx, Rychard J. Bouwens +4
We use ultradeep HST WFC3/IR imaging of the HUDF to investigate the rest-frame optical morphologies of a mass-selected sample of galaxies at z~2. We find a large variety of galaxy…
Supernova Constraints and Systematic Uncertainties from the First 3 Years of the Supernova Legacy Survey
A. Conley, J. Guy, M. Sullivan +33
We combine high redshift Type Ia supernovae from the first 3 years of the Supernova Legacy Survey (SNLS) with other supernova (SN) samples, primarily at lower redshifts, to form a…
SNLS3: Constraints on Dark Energy Combining the Supernova Legacy Survey Three Year Data with Other Probes
M. Sullivan, J. Guy, A. Conley +33
We present observational constraints on the nature of dark energy using the Supernova Legacy Survey three year sample (SNLS3) of Guy et al. (2010) and Conley et al. (2011). We use…
