100 μm and 160 μm emission as resolved star-formation rate estimators in M 33 (HERM33ES) *
Context. Over the past few years several studies have provided estimates of the SFR (star-formation rate) or the total infrared luminosity from just one infrared band. However these relations are generally derived for entire galaxies, which are known to contain a large scale diffuse emission that is not necessarily related to the latest star-formation episode. Aims. We provide new relations to ...
متن کاملCool gas and dust in M33: Results from the Herschel M33 extended survey (HERM33ES)
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. With roughly half-solar abundances, M33 is a first step towards young low-metallicity galaxies where the submm may be able to provide an alternative to CO mapping to measure their H2 content. In this Letter, we measure ...
متن کاملPACS and SPIRE photometer maps of M 33: First results of the HERschel M 33 Extended Survey (HERM33ES)*
Context. Within the framework of the HERM33ES key program, we are studying the star forming interstellar medium in the nearby, metal-poor spiral galaxy M 33, exploiting the high resolution and sensitivity of Herschel. Aims. We use PACS and SPIRE maps at 100, 160, 250, 350, and 500 μm wavelength, to study the variation of the spectral energy distributions (SEDs) with galacto-centric distance. Me...
متن کاملThermal Emission from Warm Dust in the Most Distant Quasars
We report new continuum observations of fourteen z∼6 quasars at 250 GHz and fourteen quasars at 1.4 GHz. We summarize all recent millimeter and radio observations of the sample of the thirty-three quasars known with 5.71 ≤ z ≤ 6.43, and present a study of the rest frame far-infrared (FIR) properties of this sample. These quasars were observed with the Max Plank Millimeter Bolometer Array (MAMBO...
متن کاملWarm up and cool down!
In adaption to shifts in ambient temperature, both prokaryotic and eukaryotic cells maintain physiological homeostasis by adjusting various cellular properties, including membrane lipid fluidity, the capacity to maintain proteostasis and rate of protein synthesis [1]. How cells respond to temperature changes is a fundamental question in cell physiology. Here we briefly review current understand...
