Say hi to @lellifede.bsky.social. 😉

A meeting nearby Firenze?

We also present tentative evidence that mergers contribute to AGN triggering in cluster cores.

Anri put a great effort into this work!

This paper is accepted for publication in PASJ.

We find that the merger fraction increases with redshift for all environments, showing a strong radial gradient in clusters. This suggests that galaxy merger activity is enhanced both at earlier cosmic times and in dense environments, highlighting the role of groups.

Using a new non-parametric classification scheme that combines Gini-M20 and shape asymmetry, we identify 12,666 mergers from a sample of 33,320 galaxies, validating our method against GALAXY CRUISE visual classifications.

These bright AGNs fill key gaps in the SDSS and Quaia catalogs and will serve as prime targets for future multi-wavelength studies.

Congratulations, Yunyi!

What's more?

I got to wonder if this is the end of an era for SExtractor. So, be ready for Tractor?

Exit polls show that the outcome of this election will be what has been obvious. Or, rather what should have been obvious. What’s not obvious is how quickly the country will overcome the harms done by the previous president.
