Prograde and retrograde stars in nuclear cluster mergers. Evolution of the supermassive black hole binary and the host galactic nucleus

Alessandra Mastrobuono-Battisti, Pau Amaro Seoane, Màrius Josep Fullana i Alfonso +5

We address the orbital distribution of stars in merging nuclear star clusters (NSCs) and the subsequent effects on supermassive black hole binary (SMBHB) evolution. We ran direct-s…

Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry

Gaia Collaboration, P. Panuzzo, T. Mazeh +412

Gravitational waves from black-hole merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected base…

Gaia Focused Product Release: Radial velocity time series of long-period variables

Gaia Collaboration, M. Trabucchi, N. Mowlavi +403

The third Gaia Data Release (DR3) provided photometric time series of more than 2 million long-period variable (LPV) candidates. Anticipating the publication of full radial-velocit…

Nuclear star clusters as probes of dark matter halos: the case of the Sagittarius Dwarf Spheroidal Galaxy

Robin Herlan, Alessandra Mastrobuono-Battisti, Nadine Neumayer

The Sagittarius dwarf spheroidal (Sgr dSph) galaxy is currently being accreted and disrupted by the tidal field of the Milky Way. Recent observations have shown that the central re…

A Wide View of the Galactic Globular Cluster NGC 2808: Red Giant and Horizontal Branch Star Spatial Distributions

Christian I. Johnson, Annalisa Calamida, Justin A. Kader +7

Wide-field and deep DECam multi-band photometry, combined with HST data for the core of the Galactic globular cluster NGC 2808, allowed us to study the distribution of various stel…

Searching for clues of past binary supermassive black hole mergers in nuclear star clusters

Alessandra Mastrobuono-Battisti, Go Ogiya, Oliver Hahn +1

Galaxy mergers are common processes in the Universe. As a large fraction of galaxies hosts at their centres a central supermassive black hole (SMBH), mergers can lead to the format…
