Abstract: In this paper we present a fully relativistic approach to modelling both the continuum emission and the reflected fluorescent iron line from a primary X-ray source near a Kerr black hole.

It's no secret that black holes are some of the weirdest objects in space. Their disks are fluffy like cake, and diving into one is both interesting and terrifying. Now, a group of astronomers ...

The dense stellar remnant would, if confirmed, be the closest known object to any black hole, according to preliminary research Sara Hashemi The energetic streams are together 23 million light ...

Core package to analyze gravitational-wave data, find signals, and study their parameters. This package was used in the first direct detection of gravitational waves (GW150914), and is used in the ...

Don't let the name fool you. Black holes might all have hearts of pure darkness, but many cloak themselves in rings of fire that blaze like little else in the cosmos. That doesn't mean all are ...

Jan. 27, 2025 — Researchers have pioneered an innovative method using helioseismology to measure the solar radiative opacity under extreme conditions. This groundbreaking work not only reveals ...

Within our comfortable world of causality we expect that reactions always follow an action and not vice versa. This why the recent chatter in the media about researchers having discovered ...
