Probing departures from Schwarzschild geometry with the S301 star and kilometre-baseline interferometry
Rodrigo P. Silva, Alexandre C. M. Correia, Paulo J. V. Garcia
The S301 star reaches a pericentre one tenth that of S2, opening a new regime for probing black-hole spin and departures from Schwarzschild. We develop a post-Newtonian secular Ham…
A solution to the paradox of youth in the Galactic centre
Rodrigo P. Silva, Alexandre C. M. Correia, Tjarda C. N. Boekholt +1
The supermassive black hole at the Galactic centre, Sgr A*, is surrounded by an S cluster of young stars. These stars are predominantly B-type stars, but their origin remains uncer…
Dynamical constraints on the S2 (S0-2) star possible companions
Rodrigo P. Silva, Alexandre C. M. Correia, Tjarda C. N. Boekholt +1
The center of the Galaxy harbors a supermassive black hole, Sgr\,A*, which is surrounded by a massive star cluster known as the S-cluster. The most extensively studied star in this…
Cosmic Microwave Background anisotropies generated by cosmic strings with small-scale structure
Rodrigo P. Silva, Lara Sousa, Ivan Yu. Rybak
We study the impact of kinks on the cosmic microwave background (CMB) anisotropies generated by cosmic string networks. To do so, we extend the Unconnected Segment Model to describ…
