Hierarchical mergers of stellar-mass black holes and their gravitational-wave signatures

Nature Astronomy, 2021
While most of the compact-binary mergers detected by LIGO and Virgo are expected to consist of first-generation black holes formed from the collapse of stars, others might instead be of second (or higher) generation, containing the remnants of previous ...

PlanetTXT: A Text-based Planetary System Simulation Interface for Astronomy Edutainment

International Conference on E-Education, E-Business, E-Management, and E-Learning, 2023
Planetary systems represent a set of gravitationally bounded non-stellar objects in or out of orbit around a star or star system. However, existing works for simulating exoplanetary systems other than the solar system are still limited. In this paper, we

Formation Channels of Single and Binary Stellar-Mass Black Holes

Handbook of Gravitational Wave Astronomy, 2021
These are exciting times for binary black hole (BBH) research. LIGO and Virgo detections are progressively drawing a spectacular fresco of BBH masses, spins and merger rates.

Gravitational wave astronomy with TianQin

Reports on progress in physics. Physical Society
The opening of the gravitational wave window has significantly enhanced our capacity to explore the Universe’s most extreme and dynamic sector. In the mHz frequency range, a diverse range of compact objects, from the most massive black holes at the ...

An Angular Diameter Measurement of β UMa via Stellar Intensity Interferometry with the VERITAS Observatory

Astrophysical Journal
We use the Very Energetic Radiation Imaging telescope Array System (VERITAS) imaging air Cherenkov telescope array to obtain the first measured angular diameter of β UMa at visual wavelengths using stellar intensity interferometry (SII) and independently
