My paper with Marco Calzà, Francesco Gianesello, and Max Rinaldi (proudly 100% made within the Theoretical Gravitation and Cosmology Group led by myself and Max!) , where we study the stochastic gravitational wave background signal resulting from inspiraling cosmologically coupled BHs (see this earlier news item), has been accepted for publication in Scientific Reports, part of the Nature Portfolio collection of journals (therefore making this my third proper Nature publication)! With respect to the earlier version we have slightly changed the title and explained the content of Fig. 2 much more clearly, but the main message of the paper is otherwise unchanged.

EHT and mimetic gravity paper accepted in Scientific Reports!
My paper with Mohsen Khodadi and Javad Firouzjaee, where we show that the EHT observations of M87* and Sgr A* rule out the baseline version of mimetic gravity (see this earlier news item), has been accepted for publication in Scientific Reports, part of the Nature Portfolio collection of journals (therefore making this my second proper Nature publication)! The most significant addition compared to the earlier version is a new figure with examples of null geodesics in the space-times we studied, which shows in a very clear way why their shadow properties are pathological.

Fifth forces and Bennu paper accepted in Communications Physics!
Very happy to report that my paper with Yu-Dai Tsai, Davide Farnocchia, Marco Micheli, and Luca Visinelli, where we use OSIRIS-REx tracking data for the asteroid Bennu to set new constraints on fifth forces and ultralight dark matter (see this earlier news item), has officially been accepted for publication in the prestigious Communications Physics, part of the Nature Portfolio collection of journals (it is my second time publishing in Nature journals after my 2020 book review in Nature Astronomy, but only the first time publishing a proper original scientific article)! It was quite a long journey, with a couple of rounds of revision on both the scientific and editorial sides, although overall there were no major changes to our results which, if anything, have been clarified better. You can read the preprint version of the paper on arXiv: 2309.13106.
