  • Compact Object Modeling with the StarTrack Population Synthesis Code 
    Belczynski, Krzysztof; Kalogera, Vassiliki; Rasio, Frederic A.; Taam, Ronald E.; Zezas, Andreas; Bulik, Tomasz; Maccarone, Thomas J.; Ivanova, Natalia (2008)
  • IC10 X-1/NGC300 X-1: The Very Immediate Progenitors of BH-BH Binaries 
    Bulik, Tomasz; Belczynski, Krzysztof; Prestwich, Andrea H. (2011)
    We investigate the future evolution of two extragalactic X-ray binaries: IC10 X-1 and NGC300 X-1. Each consists of a high-mass black hole (BH; ~20-30 M <SUB>sun</SUB>) accreting from a massive Wolf-Rayet (W-R) star companion ...
  • Modelling the formation of the first two neutron star-black hole mergers, GW200105 and GW200115: metallicity, chirp masses, and merger remnant spins 
    Chattopadhyay, Debatri; Stevenson, Simon; Broekgaarden, Floor; Antonini, Fabio; Belczynski, Krzysztof (2022)
    The two neutron star-black hole mergers (GW200105 and GW200115) observed in gravitational waves by advanced LIGO and Virgo, mark the first ever discovery of such binaries in nature. We study these two neutron star-black ...
  • The Origin of the Ultraluminous X-Ray Sources 
    Wiktorowicz, Grzegorz; Sobolewska, Malgorzata; Lasota, Jean-Pierre; Belczynski, Krzysztof (2017)
    Recently, several ultraluminous X-ray (ULX) sources were shown to host a neutron star (NS) accretor. We perform a suite of evolutionary calculations, which show that, in fact, NSs are the dominant type of ULX accretor. ...
  • A wide star-black-hole binary system from radial-velocity measurements 
    Liu, Jifeng; Zhang, Haotong; Howard, Andrew W.; Bai, Zhongrui; Lu, Youjun; Soria, Roberto; Justham, Stephen; Li, Xiangdong; Zheng, Zheng; Wang, Tinggui; Belczynski, Krzysztof; Casares, Jorge; Zhang, Wei; Yuan, Hailong; Dong, Yiqiao; Lei, Yajuan; Isaacson, Howard; Wang, Song; Bai, Yu; Shao, Yong; Gao, Qing; Wang, Yilun; Niu, Zexi; Cui, Kaiming; Zheng, Chuanjie; Mu, Xiaoyong; Zhang, Lan; Wang, Wei; Heger, Alexander; Qi, Zhaoxiang; Liao, Shilong; Lattanzi, Mario; Gu, Wei-Min; Wang, Junfeng; Wu, Jianfeng; Shao, Lijing; Shen, Rongfeng; Wang, Xiaofeng; Bregman, Joel; Di Stefano, Rosanne; Liu, Qingzhong; Han, Zhanwen; Zhang, Tianmeng; Wang, Huijuan; Ren, Juanjuan; Zhang, Junbo; Zhang, Jujia; Wang, Xiaoli; Cabrera-Lavers, Antonio; Corradi, Romano; Rebolo, Rafael; Zhao, Yongheng; Zhao, Gang; Chu, Yaoquan; Cui, Xiangqun (2019)
    All stellar-mass black holes have hitherto been identified by X-rays emitted from gas that is accreting onto the black hole from a companion star. These systems are all binaries with a black-hole mass that is less than 30 ...
  • The X-Ray Star Formation Story as Told by Lyman Break Galaxies in the 4 Ms CDF-S 
    Basu-Zych, Antara R.; Lehmer, Bret D.; Hornschemeier, Ann E.; Bouwens, Rychard J.; Fragos, Tassos; Oesch, Pascal A.; Belczynski, Krzysztof; Brandt, W. N.; Kalogera, Vassiliki; Luo, Bin; Miller, Neal; Mullaney, James R.; Tzanavaris, Panayiotis; Xue, Yongquan; Zezas, Andreas (2013)
    We present results from deep X-ray stacking of &gt;4000 high-redshift galaxies from z ? 1 to 8 using the 4 Ms Chandra Deep Field-South data, the deepest X-ray survey of the extragalactic sky to date. The galaxy samples ...
