The Heating of Mid-Infrared Dust in the Nearby Galaxy M33: A Testbed for Tracing Galaxy Evolution
M. Calapa, D. Calzetti, B. T. Draine +10
Because the 8 μm polycyclic aromatic hydrocarbon (PAH) emission has been found to correlate with other well-known star formation tracers, it has widely been used as a star formati…
Dust and gas power-spectrum in M33 (HERM33ES)
F. Combes, M. Boquien, C. Kramer +18
Power spectra of de-projected images of late-type galaxies in gas and/or dust emission are very useful diagnostics of the dynamics and stability of their interstellar medium. Previ…
Molecular and Atomic Gas in the Local Group Galaxy M33
P. Gratier, J. Braine, N. J. Rodriguez-Fernandez +22
We present high resolution large scale observations of the molecular and atomic gas in the Local Group Galaxy M33. The observations were carried out using the HERA at the 30m IRAM…

Boon-Kok Tan, J. Leech, D. Rigopoulou +20
We present CO \textit{J=32} maps of NGC 2976 and NGC 3351 obtained with the James Clerk Maxwell Telescope (JCMT), both early targets of the JCMT Nearby Galaxy L…
Spectral Energy Distributions of HII regions in M33 (HerM33es)
M. Relano, S. Verley, I. Perez +16
Within the framework of the Herschel M 33 extended survey HerM33es we study the Spectral Energy Distribution (SED) of a set of HII regions in M 33 as a function of the morphology.…
Properties of compact 250 μm emission and HII regions in M33 (HERM33ES)
S. Verley, M. Relaño, C. Kramer +12
Within the framework of the HERM33ES Key Project, using the high resolution and sensitivity of the Herschel photometric data, we study the compact emission in the Local Group spira…
Variation in the dust emissivity index across M33 with Herschel and Spitzer (HerM33es)
F. S. Tabatabaei, J. Braine, E. M. Xilouris +12
We study the wavelength dependence of the dust emission as a function of position and environment across the disk of M33 at a linear resolution of 160 pc using Spitzer and Herschel…
[CII] gas in IC 342
M. Röllig, R. Simon, R. Güsten +6
Methods: We used the dual-band receiver GREAT on board the SOFIA airborne telescope to perform observations of the [C II] 158 μm fine-structure line at the postitions of two giant…
Variation in the dust spectral index across M33
F. S. Tabatabaei, J. Braine, C. Kramer +9
Using the Herschel PACS and SPIRE FIR/submm data, we investigate variations in the dust spectral index in the nearby spiral galaxy M33 at a linear resolution of 160 pc. We use…
Velocity resolved [CII] spectroscopy of the center and the BCLMP302 region of M33 (HerM33es)
B. Mookerjea, F. Israel, C. Kramer +8
We aim to understand the contribution of the ionized, atomic and molecular phases of the ISM to the [CII] emission from clouds near the dynamical center and the BCLMP302 HII region…
Cool gas and dust in M33: Results from the Herschel M33 extended survey (HERM33ES)
J. Braine, P. Gratier, C. Kramer +23
We present an analysis of the first space-based far-IR-submm observations of M 33, which measure the emission from the cool dust and resolve the giant molecular cloud complexes. Wi…
[CII] 158m and [NII] 205m emission from IC 342 - Disentangling the emission from ionized and photo-dissociated regions
Markus Röllig, R. Simon, R. Güsten +3
Aims: We investigate how much of the [CII] emission in the nucleus of the nearby spiral galaxy IC 342 is contributed by PDRs and by the ionized gas. We examine the spatial variatio…
Disentangling the circumnuclear environs of Centaurus A: Gaseous Spiral Arms in a Giant Elliptical Galaxy
D. Espada, S. Matsushita, A. B. Peck +3
We report the existence of spiral arms in the recently formed gaseous and dusty disk of the closest giant elliptical, NGC 5128 (Centaurus A), using high resolution 12CO(2-1) observ…

Dust heating sources in galaxies: the case of M33 (HERM33ES)
M. Boquien, D. Calzetti, F. Combes +7
Dust emission is one of the main windows to the physics of galaxies and to star formation as the radiation from young, hot stars is absorbed by the dust and reemitted at longer wav…
Measuring star formation with resolved observations: the test case of M33
M. Boquien, D. Calzetti, S. Aalto +15
Context. Measuring star formation at a local scale is important to constrain star formation laws. Yet, it is not clear whether and how the measure of star formation is affected by…
