Using a combination of high-resolution Hubble Space Telescope/WFPC2 observations, we explore the physical properties of the stellar populations in two intermediate-age star cluster…
The Ginger-shaped Asteroid 4179 Toutatis: New Observations from a Successful Flyby of Chang'e-2
Jiangchuan Huang, Jianghui Ji, Peijian Ye +26
On 13 December 2012, Chang'e-2 conducted a successful flyby of the near-Earth asteroid 4179 Toutatis at a closest distance of 770 120 meters from the asteroid's surface. The…
Magnetic fields in Accretion Discs around Neutron Stars - Consequences for the change of spin
Luca Naso, John Miller, Wlodek Kluzniak
Accretion disks are ubiquitous in the universe and it is generally accepted that magnetic fields play a pivotal role in accretion-disk physics. The spin history of millisecond puls…
First Galaxy-Galaxy Lensing Measurement of Satellite Halo Mass in the CFHT Stripe-82 Survey
Ran Li, Huanyuan Shan, HouJun Mo +7
We select satellite galaxies from the galaxy group catalog constructed with the SDSS spectroscopic galaxies and measure the tangential shear around these galaxies with source catal…
Outflows from active galactic nuclei: The BLR-NLR metallicity correlation
Pu Du, Jian-Min Wang, Chen Hu +4
The metallicity of active galactic nuclei (AGNs), which can be measured by emission line ratios in their broad and narrow line regions (BLRs and NLRs), provides invaluable informat…
Numerical simulation of the electron capture process in a magnetar interior
Z. F. Gao, N. Wang, J. P. Yuan +2
In a superhigh magnetic field, direct Urca reactions can proceed for an arbitrary proton concentration. Since only the electrons with high energy (, is the threshold…
