Survival of black holes through a cosmological bounce
Daniela Pérez, Gustavo E. Romero
We analyze whether a black hole can exist and survive in a universe that goes through a cosmological bounce. To this end, we investigate a central inhomogeneity embedded in a bounc…
Deep Learning-Based Super-Resolution and De-Noising for XMM-Newton Images
Sam F. Sweere, Ivan Valtchanov, Maggie Lieu +6
The field of artificial intelligence based image enhancement has been rapidly evolving over the last few years and is able to produce impressive results on non-astronomical images.…
Review of opportunities for new long-lived particle triggers in Run 3 of the Large Hadron Collider
Juliette Alimena, James Beacham, Freya Blekman +75
Long-lived particles (LLPs) are highly motivated signals of physics Beyond the Standard Model (BSM) with great discovery potential and unique experimental challenges. The LLP searc…
Evolution of the energy efficiency of LHCb's real-time processing
Roel Aaij, Daniel Hugo Cámpora Pérez, Tommaso Colombo +7
The upgraded LHCb detector, due to start datataking in 2022, will have to process an average data rate of 4~TB/s in real time. Because LHCb's physics objectives require that the fu…
Black hole in asymmetric cosmological bounce
Daniela Pérez, Santiago E. Perez Bergliaffa, Gustavo E. Romero
We determine the causal structure of the McVittie spacetime for a cosmological model with an asymmetric bounce. The analysis includes the computation of trapping horizons, regular,…
Dynamical black hole in a bouncing universe
Daniela Pérez, Santiago E. Perez Bergliaffa, Gustavo E. Romero
We analyze the causal structure of McVittie spacetime for a classical bouncing cosmological model. In particular, we compute the trapping horizons of the metric and integrate the t…
Astrophysical Constraints on Strong Modified Gravity
Daniela Pérez, Gustavo E. Romero
We offer a discussion on the strong field regime predictions of two families of theories that deviate from General Relativity in different aspects: -gravity and Scalar-Tensor…
Accretion disks around black holes in Scalar-Tensor-Vector Gravity
Daniela Pérez, Federico G. Lopez Armengol, Gustavo E. Romero
Scalar Tensor Vector Gravity (STVG) is an alternative theory of gravitation that has successfully explained the rotation curves of nearby galaxies, the dynamics of galactic cluster…
High-energy signatures of binary systems of supermassive black holes
Gustavo E. Romero, Gabriela S. Vila, Daniela Pérez
Context. Binary systems of supermassive black holes are expected to be strong sources of long gravitational waves prior to merging. These systems are good candidates to be observed…
Accretion disks around black holes in modified strong gravity
Daniela Pérez, Gustavo E. Romero, Santiago E. Perez Bergliaffa
Stellar-mass black holes offer what is perhaps the best scenario to test theories of gravity in the strong-field regime. In particular, f(R) theories, which have been widely discus…
An analysis of a regular black hole interior model
Daniela Pérez, Gustavo E. Romero, Santiago E. Perez Bergliaffa
We analyze the thermodynamical properties of the regular static and spherically symmetric black hole interior model presented by Mboyne and Kazanas. Equations for the thermodynamic…
Time and irreversibility in an accelerating universe
Gustavo E. Romero, Daniela Pérez
It is a remarkable fact that all processes occurring in the observable Universe are irreversible, whereas the equations through which the fundamental laws of physics are formulated…
