Relativistic Fe K Line Revealed in the Composite X-ray Spectrum of Narrow Line Seyfert 1 Galaxies --- do their black holes have averagely low or intermediate spins?
Zhu Liu, Weimin Yuan, Youjun Lu +1
While a broad profile of the Fe K emission line is frequently found in the X-ray spectra of typical Seyfert galaxies, the situation is unclear in the case of Narrow Line Seyfert…
Reducing the Tension Between the BICEP2 and the Planck Measurements: A Complete Exploration of the Parameter Space
Yi-Chao Li, Feng-Quan Wu, You-Jun Lu +1
A large inflationary tensor-to-scalar ratio is reported by the BICEP2 team based on their B-mode polarization detection, which is outside…
Offsets between the X-ray and the Sunyaev-Zel'dovich-effect peaks in merging galaxy clusters and their cosmological implications
Congyao Zhang, Qingjuan Yu, Youjun Lu
Observations reveal that the peaks of the X-ray map and the Sunyaev-Zel'dovich (SZ) effect map of some galaxy clusters are offset from each other. In this paper, we perform a set o…
Probing baryonic processes and gastrophysics in the formation of the Milky Way dwarf satellites: I. metallicity distribution properties
Jun Hou, Qingjuan Yu, Youjun Lu
In this paper, we study the chemical properties of the stars in the dwarf satellites around the MW-like host galaxies, and explore the possible effects of several baryonic processe…
Cosmological parameter fittings with the BICEP2 data
Fengquan Wu, Yichao Li, Youjun Lu +1
Combining the latest Planck, Wilkinson Microwave Anisotropy Probe (WMAP), and baryon acoustic oscillation (BAO) data, we exploit the recent cosmic microwave background (CMB) B-mode…
On the Existence of Pulsars in the Vicinity of the Massive Black Hole in the Galactic Center
Fupeng Zhang, Youjun Lu, Qingjuan Yu
Pulsars, if existing and detectable in the immediate vicinity of the massive black hole (MBH) in the Galactic center (GC), may be used as a superb tool to probe both the environmen…
