Converting Hα Luminosities into Star Formation Rates
Abstract. The recent finding that the IGIMF (integrated galaxial initial stellar mass function) composed of all newly formed stars in all young star clusters has, in dependence of the SFR, a steeper slope in the high mass regime than the underlying canonical IMF of each star cluster offers new insights into the galactic star formation process: The classical linear relation between the SFR and t...
متن کاملThe Sizes and Luminosities of Massive Star Clusters
The masses of star clusters range over seven decades, from ten up to one hundred million solar masses. Remarkably, clusters with masses in the range 10M⊙ to 10M⊙ show no systematic variation of radius with mass. However, recent observations have shown that clusters with Mcl & 3× 10M⊙ do show an increase in size with increasing mass. We point out that clusters with Mcl & 10M⊙ were optically thic...
متن کاملThe star - burst galaxies NGC 278 , NGC 660 , NGC 3628 , NGC 4631 , and NGC 4666
Aims. We study the physical properties and mass of molecular gas in the central regions of galaxies with active nuclei. GHz [CI] maps in three of these are used to model the molecular gas. Results. All five objects contain bright CO emission in the central regions. Clear central concentrations were found in NGC 660, NGC 3628, and NGC 4666, but not in the weakest CO emitters NGC 278 and NGC 4631...
متن کاملThe Star Cluster population of NGC 5253 ⋆
We present a detailed analysis of the star cluster population in the starburst galaxy NGC 5253. Our work is based on HST optical and VLT Ks images. We detect more than 300 clusters, and for all of them we derive the photometry in the V, I and Ks bands and built a color-color V-I/V-Ks diagram. After correction for star contamination, we matched 115 sources in all the three bands V, I and Ks. Com...
متن کاملStudy of star formation in NGC 1084
We present UBV RI broad band, Hα narrow band photometry of the star forming complexes in the infra-red bright galaxy NGC 1084. Results of medium resolution spectroscopy of some of the brighter complexes are also discussed. Spectroscopic data is used to better estimate the internal reddening within the galaxy which is found to be highly variable and to calculate metallicity which is close to the...
