The Search for High-Mass X-ray Binaries in the Phoenix Dwarf Galaxy
High-Mass X-ray Binaries Phoenix Dwarf Galaxy
2012/2/23
We report on the first X-ray images of the Phoenix dwarf galaxy, taken with \emph{XMM-Newton} in July 2009. This local group dwarf galaxy shares similarities with the Small Magellanic Cloud (SMC) incl...
Evidence for Inflow in High-Mass Star-Forming Clumps
Evidence for Inflow in High-Mass Star-Forming Clumps
2011/10/17
We analyze the HCO+ 3-2 and H13CO+ 3-2 line profiles of 27 high-mass star-forming regions to identify asymmetries that are suggestive of mass inflow. Three quantitative measures of line asymmetry are ...
Outflow activities in the young high-mass stellar object G23.44-0.18
stars: pre-main sequence—ISM:molecules—ISM: individual (G23.44-0.18)—stars: formation
2011/9/29
We present an observational study towards the young high-mass star forming region G23.44-0.18 using the Submillimeter Array. Two massive, radio-quiet dusty cores MM1 and MM2 are observed in 1.3 mm con...
Jets in high-mass microquasars
X-rays: binaries–ISM: jets and outfl ows–Stars: winds, outfl ows–Radiation mechanisms: non-thermal
2011/9/28
The morphologies of detected jets in X-ray binaries are almost as diverse as their number. This is due to different jet properties and ambient media that these jets encounter. It is important to under...
Distribution of High Mass X-ray Binaries in the Milky Way
Distribution High Mass X-ray Binaries Milky Way
2011/9/27
The INTEGRAL satellite, observing the sky at high energy, has quadrupled the number of supergiant X-ray Binaries known in the Galaxy and has revealed new populations of previously hidden High Mass X-r...
OH Masers and the Dust Emissions Towards High Mass Protostellar Objects
stars: formation masers: OH masers millimeter
2011/9/27
Context: OH maser emission is known to be associated with high mass star forming regions. Towards some of these regions, OH masers are associated with HII regions. Towards others, believed to be in an...

Dissecting high-mass star-forming regions complex formation history
2011/8/24
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...
Nature, formation and evolution of High Mass X-ray Binaries

2011/9/27
The aim of this review is to describe the nature, formation and evolution of the three kinds of high mass X-ray binary (HMXB) population: i. systems hosting Be stars (BeHMXBs), ii. systems accreting t...

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 Mass X-ray Binaries in the NIR : Orbital solutions of two highly obscured systems
High Mass X-ray Binaries；the NIR
2011/1/13
The maximum mass of a neutron star (NS) is poorly defined. Theoretical attempts to define this mass have thus far been unsuccessful. Observational results currently provide the only means of narrowing...
The Interplay of Magnetic Fields, Fragmentation and Ionization Feedback in High-Mass Star Formation
Magnetic Fields Fragmentation High-Mass Star Formation
2011/1/13
Massive stars disproportionately influence their surroundings. How they form has only started to become clear recently through radiation gas dynamical simulations. However, until now, no simulation ha...
We present results from CDF and DØ on direct searches for high mass standard model (SM) Higgs boson (H) in p¯p collisions at the Fermilab Tevatron at √s = 1.96 TeV. Compared to previous Hi...
We review the most recent experimental progress in the hadron spectroscopy, up to bottomonium
mass. This covers the search for the JPC = 1−+ exotic state, the states in J/y decays, the spinsing...
