[Astro] [CAPT] Astro seminar Wed 19th Feb 15:45 C4 -- Andy Young (Bristol)

[Luke Conaboy]

Hi all,

this week our seminar is given by Andy Young (Bristol), talking about X-raying black hole accretion flows. The seminar will be in C4.

Post-seminar refreshments will be wine and cheese.

Timings are as usual:

- lunch at Lakeside, leaving CAPT ~13:00 (subsidised for a limited number of students -- let me know before the end of the day tomorrow)
- meet the speaker for postgrads at 15:00, finishing at 15:30
- seminar at 15:45 in C5/C4
- post-seminar wine and cheese at 16:45

This seminar will be conducted in person only.

Best,
Jesse and Luke

X-raying Black Hole Accretion Flows

X-ray observations of black hole accretion flows can be used to study the accretion disc, corona, and black hole spacetime. I will explain how a combination of spectroscopy and timing can be used to measure black hole spin, mass, and geometry of the accretion flow. However, existing models are incomplete because they cannot self-consistently explain all the features of observations, or model “realistic” disc and corona geometries. I will describe our recent work on producing fast, flexible, numerical models that we plan to fit to X-ray spectral timing data.
