Claudio Ricci

Astrophysicist studying supermassive black holes and other fascinating beasts of the cosmos. Faculty @unige_en and Scientific Editor @AAS_Publishing.

[Frontiers - Astronomy and Space Sciences @FrontAstroSpace]

Co-authored by S. Laha, C. Ricci (@crabnebula83) and Nobel laureate J. Mather, et al., this new review explores the mystery of X-ray coronal emission from supermassive black holes — how is it powered and sustained?

This series connects our Scientific Editors with their human story, with our authors and referees, and with the larger #astronomy community.

[Claudio Ricci @crabnebula83]

I am very excited to join the @AAS_Publishing editorial board as new scientific editor for ApJ!

The tight correlation might also suggests that the mm continuum could be produced by the X-ray corona, more on this very soon!

[Claudio Ricci @crabnebula83]

Paper day! We studied with ALMA nearby radio-quiet AGN and found a very tight correlation between the 100GHz and X-ray continuum. The mm-continuum is unaffected by obscuration up to ~1e27 cm^-2, which makes it a powerful tool to study obscured accretion https://t.co/kye1OZXLav

And here is Dr. Gupta with most of my group right after graduating

[Claudio Ricci @crabnebula83]

So proud of Kriti Kamal Gupta for being the first PhD student to graduate at the Institute of Astrophysical Studies!

A big day for our young Institute of Astrophysical Studies (IEA) @AstroUDP with the very first graduated doctoral student, Dr. Kriti Kamal Gupta!!

Congratulations to Kriti and her supervisor Prof. Ricci 🎉🍾🎉🍾

A science paper entitled, "UGC 4211: A Confirmed Dual Active Galactic Nucleus in the Local Universe at 230 pc Nuclear Separation," which details the results published today in the Astrophysical Journal Letters. 5/🧵https://t.co/NkKETt16Ha

@TM_Eubanks @bennytr I guess the best candidates would be those that are found to show repeated transitions in the optical. You could have a look at this: https://t.co/9vUpK1eb8f for the connection between binary BHs and CL AGN.

Paper day! With @bennytr we wrote a Nature Astronomy invited review on Changing-look AGN https://t.co/whVeLk5NPa

In other *non-JWST, non-high-redshift* news, my review article on AGN in LIRGs just got published and is now up on arXiv!! (It's also open access so feel free to directly peruse the prettier version at the publisher's link below.)
