Modelling galaxy clustering: halo occupation distribution versus subhalo matching [0.03%]
建模星系聚类：星系occupation分布方法与子结构匹配方法的比较研究
Hong Guo,Zheng Zheng,Peter S Behroozi et al.
Hong Guo et al.
We model the luminosity-dependent projected and redshift-space two-point correlation functions (2PCFs) of the Sloan Digital Sky Survey (SDSS) Data Release 7 Main galaxy sample, using the halo occupation distribution (HOD) model and the subh...
The minimum mass of detectable planets in protoplanetary discs and the derivation of planetary masses from high-resolution observations [0.03%]
原行星盘中可检测到的系外行星的最小质量和从高分辨率观测中推导出行星质量的方法
Giovanni P Rosotti,Attila Juhasz,Richard A Booth et al.
Giovanni P Rosotti et al.
We investigate the minimum planet mass that produces observable signatures in infrared scattered light and submillimetre (submm) continuum images and demonstrate how these images can be used to measure planet masses to within a factor of ab...
Low-radio-frequency eclipses of the redback pulsar J2215+5135 observed in the image plane with LOFAR [0.03%]
低射频红背脉冲星J2215+5135的掩食事件：LOFAR成像观测结果
J W Broderick,R P Fender,R P Breton et al.
J W Broderick et al.
The eclipses of certain types of binary millisecond pulsars (i.e. 'black widows' and 'redbacks') are often studied using high-time-resolution, 'beamformed' radio observations. However, they may also be detected in images generated from inte...
Modelling accretion disc and stellar wind interactions: the case of Sgr A [0.03%]
论质量吸积盘和恒星风的相互作用——以人马A*为例
I M Christie,M Petropoulou,P Mimica et al.
I M Christie et al.
Sgr A* is an ideal target to study low-luminosity accreting systems. It has been recently proposed that properties of the accretion flow around Sgr A* can be probed through its interactions with the stellar wind of nearby massive stars belo...

We compare the Baryonic Tully-Fisher relation (BTFR) of simulations and observations of galaxies ranging from dwarfs to spirals, using various measures of rotational velocity Vrot. We explore the BTFR when measuring Vrot at the flat part of...
Tapering the sky response for angular power spectrum estimation from low-frequency radio-interferometric data [0.03%]
基于低频射电干涉数据的角功率谱估计中的天顶响应处理方法研究
Samir Choudhuri,Somnath Bharadwaj,Nirupam Roy et al.
Samir Choudhuri et al.
It is important to correctly subtract point sources from radio-interferometric data in order to measure the power spectrum of diffuse radiation like the Galactic synchrotron or the Epoch of Reionization 21-cm signal. It is computationally v...
Cluster mass profile reconstruction with size and flux magnification on the HST STAGES survey [0.03%]
基于HST-STAGES调查的放大率重建星系团质量分布
Christopher A J Duncan,Catherine Heymans,Alan F Heavens et al.
Christopher A J Duncan et al.
We present the first measurement of individual cluster mass estimates using weak lensing size and flux magnification. Using data from the HST STAGES (Space Telescope A901/902 Galaxy Evolution Survey) survey of the A901/902 supercluster we d...

M2 has been claimed to possess three distinct stellar components that are enhanced in iron relative to each other. We use equivalent width measurements from 14 red giant branch stars from which Yong et al. detect a ∼0.8 dex wide, trimodal ...

Jean-Christophe Loison et al.
We present the detection of two H2C3O isomers, propynal and cyclopropenone, toward various starless cores and molecular clouds, together with upper limits for the third isomer propadienone. We review the processes controlling the abundances...
The abundance of 28Si32S, 29Si32S, 28Si34S, and 30Si32S in the inner layers of the envelope of IRC+10216 [0.03%]
红外源体IRC+10216包层内层中 ^28Si^32S、^29Si^32S、^28Si^34S 和 ^30Si^32S 的丰度

J P Fonfría et al.
We present high spectral resolution mid-IR observations of SiS towards the C-rich AGB star IRC+10216 carried out with the Texas Echelon-cross-Echelle Spectrograph mounted on the NASA Infrared Telescope Facility. We have identified 204 ro-vi...
