Systematic study of the composition of Type I X-ray burst ashes: Neutron star structure v.s. Reaction rate uncertainties

Kavli Affiliate: Renxin Xu | First 5 Authors: Guoqing Zhen, Helei Liu, Akira Dohi, Guoliang Lü, Nobuya Nishimura | Summary: In this study, we calculate for the first time the impacts of neutron star(NS) structure on the type I X-ray burst ashes using the texttt{MESA} code. We find an increased mass fraction of the heavier […]

FEASTS Combined with Interferometry. III. The Low-column-density HI Around M51 and Possibility of Turbulent-mixing Gas Accretion

Kavli Affiliate: Luis C. Ho | First 5 Authors: Xuchen Lin, Jing Wang, Lister Staveley-Smith, Suoqing Ji, Dong Yang | Summary: With a new joint-deconvolution pipeline, we combine the single-dish and interferometric atomic hydrogen (HI) data of M51 observed by the FAST (FEASTS program) and VLA (THINGS). The product data cube has a typical line […]

The Pristine survey: XXVIII. The extremely metal-poor stream C-19 stretches over more than 100 degrees

Zhen Yuan, Tadafumi Matsuno, Tatyana Sitnova, Nicolas F. Martin, Rodrigo A. Ibata | Summary: [[{“value”:”The discovery of the most metal-poor stream, C-19, provides us with a fossil record of a stellar structure born very soon after the Big Bang. In this work, we search for new C-19 members over the whole sky by combining two […]

Chinese Pulsar Timing Array upper limits on microhertz gravitational waves from supermassive black-hole binaries using PSR J1713+0747 FAST data

Kavli Affiliate: Kejia Lee | First 5 Authors: R. Nicolas Caballero, Heng Xu, Kejia Lee, Siyuan Chen, Yanjun Guo | Summary: We derive the gravitational-wave (GW) strain upper limits from resolvable supermassive black-hole binaries using the data from the Five-hundred-meter Aperture Spherical radio Telescope (FAST), in the context of the Chinese Pulsar Timing Array project. […]

Comparing observed properties of winds in low-luminosity active galactic nuclei with theoretical predictions

Kavli Affiliate: Feng Yuan | First 5 Authors: Fangzheng Shi, Feng Yuan, Francesco Tombesi, Fu-guo XIe, | Summary: Theoretical and numerical simulations of black hole hot accretion flows have shown the ubiquitous existence of winds and predicted their properties such as velocity and mass flux. In this paper, we have summarized from literature the physical […]
