Cool paper on arXiv today on whether we could actually save Earth from an asteroid with just six month's warning, as depicted in Don't Look Up. Turns out, yes! Probably. arxiv.org/abs/2201.10663

I'm very happy to announce the "Challenges to ΛCDM" Cosmology workshop, which will take place from 4 to 7 of September at the Aristotle University of Thessaloniki, Greece. The registration deadline is on July 29, and everyone is welcome to attend!! sites.google.com/view/cosmo-wor…

Maybe someday, women in America will have as many rights as guns do.

#ChallengeLCDM has started tonight with a great talk by Subir Sarkar, Seeing the Edge of the Universe brought us to the edge of your way of thinking!

THIS ONE IS FOR THE DINOSAURS

It's the cat's birthday

A fun paper and an example of interdisciplinary work --with cosmologists (George Alestas George Alestas and Savvas Nesseris) and string theorists (Matilda Delgado Maldita Delgado, Ignacio Ruiz nacho, and Miguel Montero Miguel Montero Muñoz): arxiv.org/abs/2406.09212

La inteligencia artificial deja de ser una "caja negra" en cosmología 😵 Nuevo estudio explora la distribución de galaxias mediante Aprendizaje Automático Interpretable. ✍️Publicado en Physical Review Letters 👤 Indira Ocampo Justiniano, Savvas Nesseris, George Alestas, Dr Domenico Sapone

Here is our new The COMPACT Collaboration paper, where we demonstrate that cosmic microwave background (CMB) polarization measurements from upcoming experiments can provide new avenues for detecting cosmic topology (i.e., the shape of the Universe): arxiv.org/abs/2503.08671

To both cosmology and string theory communities: do not use simple phenomenological parametrizations (e.g., truncated Taylor expansions) of dark energy equation of state to conclude whether or not dark energy is dynamical -- see our recent paper: arxiv.org/abs/2503.22529
