Dr Christopher Berry

Hello

I'm a gravitational-wave astronomer researching the formation and evolution of black holes and neutron stars

I primarily work on LIGO–Virgo–KAGRA data analysis, inferring source properties, but I'm also interested in space-based observatories like LISA

I enjoy (I want to get back into blogging cplberry.com/blog/), and I'm currently a member of the community-science Gravity Spy project gravityspy.org/

I also like cake

My avatar pic is a doodle I drew for a LIGO Magazine article about how we infer the properties of a source for the signal, for example how we measure the masses of merging black holes

The Doodle shows Monty and Carla exploring the distribution of source masses. The names are a pun as we use Markov-chain Monte Carlo samplers as part of our analysis

Gravitational-wave astronomy uses observations of gravitational waves—ripples in spacetime created by accelerating masses—to learn about the Universe. But how do we go from gravitational-wave data to measuring the masses of the black holes that emitted the signal?

This infographic explains how information about the properties of a binary black hole coalescence is encoded in the waveform

@cplberry tbh, it was the “may contain traces of nuts” in your bio that was the deciding factor for the follow. 😂 Welcome from a fellow newbie. 🍺

@mmylova Thank you! Monty and Carla are pleasantly round. They are shaped like friends. All inference algorithms should be friendly
