Modeling and predicting the shape of the far-infrared to submillimeter emission in ultra-compact HII regions and cold clumps⋆
Context. Dust properties are very likely affected by the environment in which dust grains evolve. For instance, some analyses of cold clumps (7 K17 K) indicate that the aggregation process is favored in dense environments. However, studying warm (30 K-40 K) dust emission at long wavelength (λ>300 μm) has been limited because it is difficult to combine far infrared-to-millimeter (FIR-to-mm) spec...
متن کاملANOMALOUS MICROWAVE EMISSION FROM THE Hii REGION RCW175
We present evidence for anomalous microwave emission in the RCW175 Hii region. Motivated by 33 GHz 13 resolution data from the Very Small Array (VSA), we observed RCW175 at 31 GHz with the Cosmic Background Imager (CBI) at a resolution of 4. The region consists of two distinct components, G29.0-0.6 and G29.1-0.7, which are detected at high signal-to-noise ratio. The integrated flux density is 5...
متن کاملHerMES: the far-infrared emission from dust-obscured galaxies
Dust-obscured galaxies (DOGs) are an ultraviolet-faint, infrared-bright galaxy population that reside at z ∼ 2 and are believed to be in a phase of dusty star-forming and active galactic nucleus (AGN) activity.We present far-infrared (far-IR) observations of a complete sample of DOGs in the 2 deg of the Cosmic Evolution Survey. The 3077 DOGs have 〈z〉 = 1.9 ± 0.3 and are selected from 24μm and r...
متن کاملThe Evolution of Far-infrared Co Emission from Protostars
We investigate the evolution of far-IR CO emission from protostars observed with Herschel/PACS for 50 sources from the combined sample of HOPS and DIGIT Herschel key programs. From the uniformly sampled spectral energy distributions, whose peaks are well sampled, we computed the Lbol, Tbol,and L L bol smm for these sources to search for correlations between far-IR CO emission and protostellar ...
متن کاملAnomalous emission from HII regions
Spinning dust appears to be the best explanation for the anomalous emission that has been observed at ∼ 10 − 60 GHz. One of the best examples of spinning dust comes from a HII region in the Perseus molecular cloud. Observations of other HII regions also show tentative evidence for excess emission at frequencies ∼ 30 GHz, although at lower emissivity levels. A new detection of excess emission at...
