Exploring the Nature of Weak Chandra Sources near the Galactic Centre
Accretion binaries X-rays
2014/12/24
We present results from the first near-IR imaging of the weak X-ray sources discovered in the Chandra/ACIS-I survey (Wang et al. 2002) towards the Galactic Centre (GC). These ~800 discrete sources, wh...
Exploring The Scaling Laws Of Star Formation
Pure sciences Star formation Scaling laws Large scale stars Galaxy formation Molecular gas
2014/12/9
Despite the well-established global Schmidt-Kennicutt (S-K) law which already serves as an essential prescription for large scale star formation in modeling and simulating galaxy formation and evoluti...
We present a detailed X-ray and radio wavelength study of G308.4-1.4, a candidate supernova remnant (SNR) in the ROSAT All Sky Survey and the MOST supernova remnant catalogue.
New Method for Exploring Super-Eddington AGNs by Near-infrared Observations
accretion: accretion disc—black hole physics— galaxies:active
2011/10/8
We propose a new method to explore the candidate super-Eddington active galactic nuclei (AGNs). We examine the properties of infrared (IR) emission from the inner edge of the dusty torus in AGNs, whic...
Exploring the Nature of the Brightest Hyper-luminous X-ray Source
accretion accretion disks – X-rays binaries – X-rays individual (ESO 243-49 HLX-1)
2010/11/11
The small subset of hyper-luminous X-ray sources with luminosities in excess of 1041 erg s−1 are hard to explain without the presence of an intermediate mass black hole, as significantly super-...
Exploring the connection of weak winds and magnetic fields
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/28
The theory of radiatively driven winds successfully explains the key points of the stellar winds of hot massive stars. However, there is an apparent break-down of this paradigm at L/Lsun<5.2: the stel...
ZEUS-2: a second generation submillimeter grating spectrometer for exploring distant galaxies
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2010/12/27
ZEUS-2, the second generation (z)Redshift and Early Universe Spectrometer, like its predecessor is a moderate resolution (R~1000) long-slit, echelle grating spectrometer optimized for the detection of...
