PPGF UNIFAL-MG/UFSJ International Conference on Multimessenger Astrophysics

17 Jul 2024, 09:30 → 19 Jul 2024, 17:00 America/Sao_Paulo

Building F Auditorium (Universidade Federal de Alfenas (UNIFAL-MG))

In recent years, Astrophysics has been undergoing a true revolution driven by access to data from new messengers such as gravitational waves and astrophysical neutrinos. 

In order to present the theme to the most extended as possible regions of Brazil and the world, the conference is jointly efford between local universities and international ones, including: the Department of Physics and Astronomy “E. Majorana” of the University of Catania, the Federal University of Alfenas (UNIFAL), the Technological Institute of Aeronautics (ITA), Sao Paulo State university (UNESP) and Federal University of Rio Grande do Norte (UFRN).

This meeting aims to bring together experts in theory, observation, and experiments studying multimessenger phenomena to review the current status and discuss on the matter.

The event targets undergraduate and postgraduate students interested in the topic, presenting an introductory course on gravitational wave astrophysics in the afternoon as well as lectures on the state of the art in the area. Mornings will be reserved for seminars from experts in the field and a poster session is planned for young researches to present their contributions.

Two extra sessions focused on scientific dissemination to the general public are planed: a chit chat in a local pub and a seminar with sky observation at on of the most iconic places of the city.

• Iara Tosta e Melo (UniCT-Italia)
• Márcio Eduardo da Silva Alves (UNESP)

16:00 → 16:30 Oral Comunication: Exploring the Higher-Order Extension of Starobinsky Inflation: Dynamics and Reheating

Higher-order theories of gravity are extensions to general relativity motivated mainly by high-energy physics searching for general relativity ultraviolet completeness. They are characterized by the inclusion of correction terms in the Einstein-Hilbert action that leads to higher-order field equations. In particular, we are interested in analyzing higher-order extension of Starobinsky inflation, namely, R³ and R□R. We investigate inflation within the Friedmann cosmological background, where we study the phase space of the model, as well as explore inflation in slow-roll leading-order. Furthermore, we describe the evolution of scalar perturbations. Finally, we confront the proposed model with recent observations from Planck, BICEP3/Keck, and BAO data.

Convener: Mr Jeremias Bezerra-Sobrinho (UFRN)

16:30 → 17:00 Oral Comunication: Dense nuclear matter in the era of multimensenger astronomy

The equation of state (EoS) of compact objects incorporate ingredients that are dependent on adjustable parameters and existing simulations allow for a wide range of energy and pressure densities, temperatures and electromagnetic fields. There is a pursuit for an EoS that adequately describes the properties expected according to theoretical nuclear physics and are also compatible with astrophysical observations. Astrophysical data made available by the Laser Interferometer Gravitational Wave Observatory/Virgo, such as events GW170817 and GW1900425, as well as traces of radioactive decay due to nucleosynthesis processes after merger of neutron stars (as the ones registered due to Kilonova event AT2017gfo), can impose restrictions on the maximum mass and radius that can be observed for these compact objects. In this talk, we will present a review of the current literature on how some nuclear physical quantities can be constrained from multi-messenger astronomical data.
