Herschel Key Program Heritage: a Far-Infrared Source Catalog for the Magellanic Clouds
Boyer, Martha L.; Matsuura, Mikako; Meixner, Margaret +19 more
Observations from the HERschel Inventory of the Agents of Galaxy Evolution (HERITAGE) have been used to identify dusty populations of sources in the Large and Small Magellanic Clouds (LMC and SMC). We conducted the study using the HERITAGE catalogs of point sources available from the Herschel Science Center from both the Photodetector Array Camera…
Herschel Observations of Circinus X-1 during Outburst and Quiescence
Harrison, Thomas E.; Gelino, Dawn M.; Buxton, Michelle +1 more
We have used the Photodetector Array Camera and Spectrometer and Spectral and Photometric Imaging REceiver instruments on the Herschel Space Observatory to observe Cir X-1 both in and out of outburst. We detected Cir X-1 during outburst at 70 µm. Unfortunately, a cold background source dominates Cir X-1 at longer wavelengths. We have assembl…
A Magnified View of Star Formation at z = 0.9 From Two Lensed Galaxies
Veilleux, Sylvain; Rigby, Jane R.; Swinbank, Mark +1 more
We present new narrowband Hα imaging from the Hubble Space Telescope of two z = 0.91 galaxies that have been lensed by the foreground galaxy cluster A2390. These data probe spatial scales as small as ~0.3 kpc, providing a magnified look at the morphology of star formation at an epoch when the global star formation rate (SFR) was high. However, dus…
