Massive star formation around I05345+3157 -- I. The dense gas
infrared:associations: individual (IRAS05345+3157) – radio continuum:interferometric
2011/9/29
We present observations of the intermediate to massive star-forming region I05345+3157 using the molecular line tracer CS(2-1) with CARMA to reveal the properties of the dense gas cores. Seven gas cor...
Feedback Regulated Star Formation: From Star Clusters to Galaxies
Feedback Regulated Star Formation Clusters Galaxies
2011/9/28
This paper summarises results from semi-analytical modelling of star formation in protocluster clumps of different metallicities. In this model, gravitationally bound cores form uniformly in the clump...
Probing cluster formation under extreme conditions: massive star clusters in blue compact galaxies
galaxies: starburst - galaxies: star clusters: general - galaxies: irregular- galaxies:star formation
2011/9/27
The numerous and massive young star clusters in blue compact galaxies (BCGs) are used to investigate the properties of their hosts. We test whether BCGs follow claimed relations between cluster popula...
Star formation history, double degenerates and type Ia supernovae in the thin disc
stars: white dwarfs − stars: evolution − stars: binaries: close − supernovae: general − Galaxy: evolution − Galaxy: structure
2011/9/27
We investigate the relation between the star formation history and the evolution of the double-degenerate (DD) population in the thin disc of the Galaxy, which we assume to have formed 10 Gyr before t...
Star formation in the extended gaseous disk of the isolated galaxy CIG 96
extended gaseous disk isolated galaxy CIG 96
2011/9/27
We study the Kennicutt-Schmidt star formation law and efficiency in the gaseous disk of the isolated galaxy CIG 96 (NGC 864), with special emphasis on its unusually large atomic gas (HI) disk (r_HI/r_...
Galaxy Structure and Mode of Star Formation in the SFR-Mass Plane from z ~ 2.5 to z ~ 0.1
Galaxy Structure Star Formation SFR-Mass Plane
2011/9/27
We analyze the dependence of galaxy structure (size and Sersic index) and mode of star formation (\Sigma_SFR and SFR_IR/SFR_UV) on the position of galaxies in the SFR versus Mass diagram. Our sample c...
Dissecting high-mass star-forming regions; tracing back their complex formation history
high-mass star-forming regions tracing complex formation
2011/9/26
We present near-infrared JHKs imaging as well as K-band multi-object spectroscopy of the massive stellar content of W3 Main using LUCI at the LBT. We confirm 13 OB stars by their absorption line spect...
High Lundquist Number Resistive MHD Simulations of Magnetic Reconnection: Searching for Secondary Island Formation
Lundquist Number Resistive MHD Simulations Magnetic Reconnection
2011/9/9
Recently, secondary island formation due to the tearing instability of the Sweet-Parker current sheet was identified as a possible mechanism that can lead to fast reconnection (less sensitive dependen...
SGRs and AXPs：Evidence for Delayed Amplification of Magnetic Field after Neutron Star Formation?
Anomalous X-ray Pulsars soft gamma-ray repeaters supernova remnants
2009/9/4
We present new analysis of the birth rate of AXPs and SGRS and their associated SNRs. Using Kolmogorov-Smirnov statistics together with parametric fits based on a robust estimator, we find a birth rat...
