On the augmented density of a spherical anisotropic dynamic system
J. An
This paper presents a set of new conditions on the augmented density of a spherical anisotropic system that is necessary for the underlying two-integral phase-space distribution fu…
Five E+A (post-starburst) galaxies as Brightest Cluster Galaxies
Feng-Shan Liu, Zhong-Lue Wen, Jin-Lin Han +1
Brightest Cluster Galaxies (BCGs) are mostly elliptical galaxies and very rarely have prominent star formation. We found that five out of 8,812 BCGs are E+A (i.e. post-starburst) g…
Tycho SN 1572: A Naked Ia Supernova Remnant without Associated Ambient Molecular Cloud
Wenwu Tian, Denis A. Leahy
The historical supernova remnant (SNR) Tycho SN 1572 originates from the explosion of a normal Type Ia supernova which is believed to have originated from a carbon-oxygen white dwa…
HIFLUGCS: Galaxy cluster scaling relations between X-ray luminosity, gas mass, cluster radius, and velocity dispersion
Y. -Y. Zhang, H. Andernach, C. A. Caretta +5
We present relations between X-ray luminosity and velocity dispersion (L-sigma), X-ray luminosity and gas mass (L-Mgas), and cluster radius and velocity dispersion (r500-sigma) for…
A New Method to Study the Origin of the EGB and the First Application on AT20G
Ming Zhou, Jiancheng Wang, Xiaoyan Gao
In this letter, we introduce a new method of image stacking to directly study the undetected but possible gamma-ray point sources. Applying the method to the Australia Telescope 20…
Modified Virial Formulae and the Theory of Mass Estimators
J. An, N. W. Evans
We show how to estimate the enclosed mass from the observed motions of an ensemble of test particles. Traditionally, this problem has been attacked through virial or projected mass…
Infall and outflow detections in a massive core JCMT 18354-0649S
Tie Liu, Yuefang Wu, Qizhou Zhang +3
We present a high-resolution study of a massive dense core JCMT 18354-0649S with the Submillimeter Array. The core is mapped with continuum emission at 1.3 mm, and molecular lines…
Estimation of absorption line indices of early-type galaxies using colours
Zhongmu LI, Ruheng LI, Ruxi LI
Context. Absorption line indices are widely used to determine the stellar population parameters such as age and metallicity of galaxies, but it is not easy to obtain the line indic…
Long-term Hard X-ray Monitoring of 2S 0114+65 with INTEGRAL/IBIS
Wei Wang
(abridged) We present the results of the long-term hard X-ray monitoring of the high mass X-ray binary 2S 0114+65 with INTEGRAL/IBIS from 2003 to 2008. 2S 0114+65 is a variable har…
Submillimeter/millimeter observations of the molecular clouds associated with the Tycho' Supernova Remnant
Jin-Long Xu, Jun-Jie Wang, Martin Miller
We have carried out CO J=2-1 and CO J=3-2 observations toward Tycho's supernova remnant (SNR) using the KOSMA 3m-Telescope. From these observations we identified three molecular cl…
Stellar metallicities beyond the Local Group: the potential of J-band spectroscopy with extremely large telescopes
C. J. Evans, B. Davies, R. -P. Kudritzki +7
We present simulated J-band spectroscopy of red giants and supergiants with a 42m European Extremely Large Telescope (E-ELT), using tools developed toward the EAGLE Phase A instrum…
A Pilot Study for the SCUBA-2 'All-Sky' Survey
Todd Mackenzie, Filiberto G. Braglia, Andy G. Gibb +30
We have carried out a pilot study for the SCUBA-2 'All-Sky' Survey, SASSy, a wide and shallow mapping project at 850 microns, designed to find rare objects, both Galactic and extra…
Redshift-Space Enhancement of Line-of-Sight Baryon Acoustic Oscillations in the SDSS Main-Galaxy Sample
H. J. Tian, Mark C. Neyrinck, Tamás Budavári +1
We show that redshift-space distortions of galaxy correlations have a strong effect on correlation functions with distinct, localized features, like the signature of the baryon aco…
An investigation of magnetic field distortions in accretion discs around neutron stars - II. Analysis of the toroidal field component
L. Naso, J. C. Miller
Millisecond pulsars are believed to be old pulsars spun up by a surrounding accretion disc. Magnetic fields are thought to play a leading role in this, both by determining the loca…
Microwave Quasi-periodic Pulsations in Multi-timescales Associated with a Solar Flare/CME Event
Baolin Tan, Yin Zhang, Chengming Tan +1
Microwave observations of quasi-periodic pulsations (QPP) in multi-timescales are confirmed to be associated with an X3.4 flare/CME event at Solar Broadband Radio Spectrometer in H…
A Sino-German 6 cm polarization survey of the Galactic plane III. The region from 10 degree to 60 degree longitude
X. H. Sun, W. Reich, J. L. Han +4
(Abridged) We have conducted a total intensity and polarization survey of the Galactic plane at 6 cm using the Urumqi 25 m telescope for the Galactic longitude range of 10 deg<l<60…
Estimating black hole masses of blazars
Xue-Bing Wu, F. K. Liu, M. Z. Kong +2
Estimating black hole masses of blazars is still a big challenge. Because of the contamination of jets, using the previously suggested size -- continuum luminosity relation can ove…
Spin Period Evolution of Recycled Pulsar in Accreting Binary
J. Wang, C. M. Zhang, Y. H. Zhao +3
We investigate the spin-period evolutions of recycled pulsars in binary accreting systems. Taking both the accretion induced field decay and spin-up into consideration, we calculat…
