How Strong Are Black Holes Really?（图）
Strong Black Holes
font style='font-size:12px;'>
2017/12/19
Black holes are famous for their muscle: an intense gravitational pull known to gobble up entire stars and launch streams of matter into space at almost the speed of light.It turns out the reality may...
Strong Electroweak Phase Transitions in the Standard Model with a Singlet
Strong Electroweak Phase Transitions Standard Model Singlet
font style='font-size:12px;'>
2011/10/14
It is well known that the electroweak phase transition (EWPhT) in extensions of the Standard Model with one real scalar singlet can be first-order for realistic values of the Higgs mass. We revisit th...

The early-type chemically peculiar stars often show strong magnetic fields on their surfaces. These magnetic topologies are organized on large scales and are believed to be close to an oblique dipole ...
Strong [O III] and [N II] emission lines in globular clusters from photoionized R Corona Borealis star winds

2011/1/13
The globular cluster X-ray source CXO J033831.8-352604 in NGC 1399 has recently been found to show strong emission lines of [O III] and [N II] in its optical spectrum in addition to ultraluminous X-ra...

2010/11/15
Using new photometric and spectroscopic data in the fields of nine strong gravitational lenses that lie in galaxy groups, we analyze the effects of both the local group environment and line-of-sight g...
Studies of Diffuse Interstellar Bands. V. Pairwise Correlations of Eight Strong DIBs and Neutral Hydrogen, Molecular Hydrogen, and Color Excess
ISM lines and bands − ISM molecules
font style='font-size:12px;'>
2010/11/15
We establish correlations between equivalent widths of eight diffuse interstel-lar bands (DIBs), and examine their correlations with atomic hydrogen, molec-ular hydrogen, and EB−V . The DIBs are...
Detection of Strong Millimeter Emission from the Circumstellar Dust Disk Around V1094 Sco: Cold and Massive Disk around a T Tauri Star in a Quiescent Accretion Phase?
stars circumstellar matter — stars individual formation
font style='font-size:12px;'>
2010/11/9
We present the discovery of a cold massive dust disk around the T Tauri star V1094 Sco in the Lupus molecular cloud from the 1.1 millimeter continuum observations with AzTEC on ASTE. A compact (r .320...
Gemini/GMOS Spectroscopy of 26 Strong Lensing Selected Galaxy Cluster Cores
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
font style='font-size:12px;'>
2011/1/4
We present results from a spectroscopic program targeting 26 strong lensing cluster cores that were visually identified in the Sloan Digital Sky Survey (SDSS) and the Second Red-Sequence Cluster Surve...
Identification of strong photometric activity in the components of LHS 1070
Solar and Stellar Astrophysics (astro-ph.SR)

2010/12/27
Activity in low-mass stars is an important ingredient in the evolution of such objects. Fundamental physical properties such as age, rotation, magnetic field are correlated with activity.
Effects of Strong Gravitational Lensing on mm-wave Galaxy Number Counts
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
font style='font-size:12px;'>
2010/12/24
We study the effects of strong lensing on the observed number counts of mm sources using a ray tracing simulation and two number count models of unlensed sources.
Cosmography with cluster strong lenses: the influence of substructure and line-of-sight halos
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
font style='font-size:12px;'>
2010/12/22
We explore the use of strong lensing by galaxy clusters to constrain the dark energy equation of state and its possible time variation. The cores of massive clusters often contain several multiply ima...

2010/3/8
We present new radial velocity measurements of the ultra-cool dwarf VB 10, which was recently announced to host a giant planet detected with astrometry. The new observations were obtained using optica...
