Investigating Galactic binary cluster candidates with Gaia EDR3
M. S. Angelo, J. F. C. Santos, F. F. S. Maia +1
A number of stellar open cluster (OC) pairs in the Milky Way occupy similar positions in the phase space (coordinates, parallax and proper motions) and therefore may constitute phy…
Advances towards the systematization of calculations with Implicit Regularization
B. Z. Felippe, A. P. Baêta Scarpelli, A. R. Vieira +1
There is currently a high demand for theoretical predictions for processes at next-to-next-to-leading order (NNLO) and beyond, mainly due to the large amount of data which has alre…
Hypermassive quark cores
Luiz L. Lopes, Carline Biesdorf, Débora P. Menezes
Using a quantum hadrodynamics (QHD) and MIT based models we construct hybrid stars within the Maxwell criteria of hadron-quark phase transition. We are able to produce a hybrid sta…
One-loop calculations in CPT-even Lorentz-breaking scalar QED
A. P. Baêta Scarpelli, J. C. C. Felipe, L. C. T. Brito +1
In this paper, we study a CPT-even Lorentz-breaking extension of the scalar QED. For this theory, we calculate the one-loop lower-order contributions in the Lorentz-violating param…
On the nature of the mass-gap object in the GW190814 event
Luiz L. Lopes, Debora P. Menezes
In this work, we make a very extensive study on the conditions that allow the mass-gap object in the GW190814 event to be faced as a degenerate star instead of a black hole. We beg…
SiS formation in the interstellar medium through Si+SH gas phase reactions
V. C. Mota, A. J. C. Varandas, E. Mendoza +2
Silicon monosulfide is an important silicon bearing molecule detected in circumstellar envelopes and star forming regions. Its formation and destruction routes are not well underst…
Entanglement entropy in multi-leg Kitaev ladders with interface defects
Dalson Eloy Almeida
The entanglement of different parts of a quantum system is expected to be proportional to the common interface area. Therefore alterations across the interface will lead to changes…
Residual gauge-invariance in a massive Lorentz-violating extension of QED
B. Alves Marques, A. P. Baêta Scarpelli, J. C. C. Felipe +1
We reassess an alternative CPT-odd electrodynamics obtained from a Palatini-like procedure. Starting from a more general situation, we analyze the physical consistency of the model…
Network diffusion capacity unveiled by dynamical paths
T. A. Schieber, L. C. Carpi, P. M. Pardalos +3
Improving the understanding of diffusive processes in networks with complex topologies is one of the main challenges of today's complexity science. Each network possesses an intrin…
Analyzing Flight Delay Prediction Under Concept Drift
Lucas Giusti, Leonardo Carvalho, Antonio Tadeu Gomes +3
Flight delays impose challenges that impact any flight transportation system. Predicting when they are going to occur is an important way to mitigate this issue. However, the behav…
New star clusters discovered towards the Galactic bulge direction using Gaia DR2
Filipe A. Ferreira, W. J. B. Corradi, F. F. S. Maia +2
We report the discovery of 34 new open clusters and candidates as a result of a systematic search carried out in 200 adjacent fields of 1x1 square degrees area projected towards th…
A min-max regret approach for the Steiner Tree Problem with Interval Costs
Iago A. Carvalho, Amadeu A. Coco, Thiago F. Noronha +1
Let G=(V,E) be a connected graph, where V and E represent, respectively, the node-set and the edge-set. Besides, let Q \subseteq V be a set of terminal nodes, and r \in Q be the ro…
