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…
Anisotropic Quark Stars with an Interacting Quark Equation of State within the Complexity Factor Formalism
Angel Rincon, Grigoris Panotopoulos, Ilidio Lopes
Within the framework of Einstein's General Relativity we study strange quark stars assuming an interacting equation-of-state. Taking into account the presence of anisotropies in a…
Hybrid star phenomenology from the properties of the special point
Christoph Gärtlein, Oleksii Ivanytskyi, Violetta Sagun +1
We study the properties of hybrid stars containing a color superconducting quark matter phase in their cores, which is described by the chirally symmetric formulation of the confin…
Quasi-equilibrium configurations of binary systems of dark matter admixed neutron stars
Hannes R. Rüter, Violetta Sagun, Wolfgang Tichy +1
Using an adapted version of the SGRID code, we construct for the first time consistent quasi-equilibrium configurations for a binary system consisting of two neutron stars in which…
Gravitational collapse and odd-parity black hole perturbations in Minimal Theory of Bigravity
Masato Minamitsuji, Antonio De Felice, Shinji Mukohyama +1
In the former part, we study the gravitational collapse of pressureless dust and find special solutions, where, in both the physical and fiducial sectors, the exterior and interior…
Dissecting the active galactic nucleus in Circinus -- III. VLT/FORS2 polarimetry confirms dusty cone illuminated by a tilted accretion disc
Marko Stalevski, Santiago González-Gaitán, Đorđe Savić +4
We present polarimetric maps of the Circinus galaxy nucleus in the bands, obtained with VLT/FORS2. Circinus is the closest Seyfert 2 galaxy and harbours an archetypal obscur…
