Astronomers have obtained observations of the smallest asteroid ever characterized in detail. At 2 meters (6 feet) in diameter, the tiny space rock is small enough to be straddled by a person in a hyp...
2016年4月5日下午,国际著名空间和大气化学专家、英国利兹大学化学研究与创新中心主任、Priestley国际气候中心副主任、2005年英国皇家化学会化学反应机制动力学奖获得者John Plane教授在水上报告厅为我校师生作了题为“宇宙尘埃、彗星、流星和气候”(Cosmic Dust, Comets, Meteors and Climate)的学术报告。本次报告为“地球和空间科学杰出讲座”系列报告...
The globular cluster population in M87 has decreased measurably through dynamical evolution caused by relaxation, binary heating and time-dependent tidal perturbation. For fundamental plane elliptical...
About 2500 square degrees of sky south of declination -25 degrees and/or near the galactic plane were surveyed for bright outer solar system objects. This survey is one of the first large scale southe...
We jointly constrain the LF and BHMF of quasars using a Bayesian approach that describes the underlying active BHMF and Eddington ratio distribution to match the observed distributions in the quasar m...
Supernova remnants (SNRs) were often discovered in radio surveys of the Galactic plane. Because of the surface-brightness limit of previous surveys, more faint or confused SNRs await discovery. The Si...
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...
Recently the H.E.S.S. collaboration announced the detection of an unidentified gamma-ray source with an off-set from the galactic plane of 3.5 degrees: HESS J1507-622. If the distance of the object is...
Context: The detection of gamma-rays in the very-high-energy (VHE) range (100 GeV-100 TeV) offers the possibility of studying the parent population of ultrarelativistic particles found in astrophysica...
Large mosaic multiCCD camera is the key instrument for modern digital sky survey. DECam is an extremely red sensitive 520 Megapixel camera designed for the incoming Dark Energy Survey (DES). It is con...
The Bolocam Galactic Plane Survey (BGPS) data for a six square degree region of the Galactic plane containing the Galactic center is analyzed and com-pared to infrared and radio continuum data. The BG...
We estimated the dynamical surface mass density () at the solar Galactocentric distance between 2 and 4 kpc from the Galactic plane, as inferred from the observed kinematics of the thick disk. We fin...
We present X-ray, infrared, optical and radio observations of four previously unidentified Galactic plane Xray sources, AX J163252–4746, AX J184738–0156, AX J144701–5919 and AX J144547–5931. Detection...
We report that the reported sub-Eddington boundary in the quasar mass-luminosity plane (a departure from the Eddington luminosity limit for the highest quasar black hole masses at a given redshift) is...
We present the Bolocam Galactic Plane Survey (BGPS), a 1.1 mm continuum survey at 3300 e ective resolution of 170 square degrees of the Galactic Plane visible from the northern hemisphere.The BGPS is ...
