Welcome to my personal webpage!
This is my personal webpage under construction (maybe forever), here you will find some information about my
personal and academic life.
My signature proving ownership of this can be found here.
I was born in Igarapé-Miri and raised in Barcarena, two cities of Pará, in the north of Brazil. I have lived in Igarapé-Miri, Barcarena, Belém, São José dos Campos, Rome and Commerce. Currently, I am living in Bogotá.
Here you can find my photos around of the world.
I am a theoretical physicist with interest in nuclear and relativistic astrophysics, gravitation and cosmology, my
research focuses on the theoretical exploration of the properties of strongly interacting matter at ultra-high
densities and temperatures, structure and evolution of compact stars (white dwarfs, neutron stars, pulsars,
magnetars, quarks stars), supernovae, wormholes, emission mechanisms (electromagnetic and gravitational) of white
dwarfs and neutron stars, ultrastrong electromagnetic fields (production of X and gamma rays), cosmic rays,
higher-dimensional and alternatives theories of gravity. More information about my academic life you can find in my
Researchgate, Curriculum Vitae or Currículo Lattes (in Portuguese). My up to date publication
list can be found on the Inspirehep database and
also on Google Scholar.
I maintain a Theoretical Physics Reference guide which is based on "How to become a GOOD Theoretical Physicist "by Gerard 't Hooft and a Data Science Reference guide for data science, machine learning, big data and related stuff.
Since 2009 I use GNU/Linux, starting with Mandriva Linux and experimenting with Ubuntu → Slackware → Fedora → Debian, since 2014 I am using Arch Linux, remaining up to now due to its principles. Here a list of my installed packages (which can be easily retrieved and installed) to do research in computational physics/astrophysics/data science and everything else. The majority of packages are handled as dependencies:, I do like to maintain a minimum list/system, and if you don't use an arch-based system I would recommend you to see this explicitly software package list instead. I also have been using Gentoo, a highly flexible, source-based Linux distribution. Since it appeals to Linux users who want a full control of the software that is installed and running on their compute, it requires time to configure and tune, so I recomend Arch as an out-of-the-box experience.

About life, our importance, politics and philosophy
In my life, I am going by my self-rules.
About our importance in the Universe: "On the scale of worlds, humans are inconsequential, a thin film of life on an obscure and solitary lump of rock and metal." Carl Sagan, speech at Cornell University, October 13, 1994.
About politics: "A dispute of Interests masked as a contest of principles. Conducting public affairs to private advantage."Here you can find my personal blog (mostly in Portuguese) where I stole some ideas ;-p
I maintain broad interests in philosophy, I advocate the Stoicism, a school of Hellenistic philosophy that flourished throughout the Roman and Greek. I also follow theses: Utilitarianism, Philosophy of the GNU Project, Unix philosophy, Eric's Random Writings, Voltaire and the great speech that I heard is that.
I am against SPAM (“Unsolicited Commercial Email”, UCE; and/or “Unsolicited Bulk Email”, UBE) (you can use a computer program for e-mail spam filtering) and support widespread use of strong cryptography for privacy, and encourage you to use GnuPG encryption with this key (GnuPG 4096 RSAv2 key: UID: 0x7E8BF5C5) when sending me emails. "Privacy isn't about hiding bad things. It's about protecting what makes us humans: our day-to-day behavior, our personality, our fears, our relationships, and our vulnerabilities. Everyone deserves privacy online." ”Arguing that you don’t care about the right to privacy because you have nothing to hide is no different than saying you don’t care about free speech because you have nothing to say.” Be ware privacy/security is inversely proportional to convenience.
You can message/audio-video call me in an end-to-end encrypted (e2ee) chat/audio-video call on Jami, this is completely peer-to-peer (p2p) and doesn't require any server for relaying data between users, i.e., one can find others through a distributed computing network and talk directly without a third-party, leaving the power of privacy and freedom in the hands of users. I highly recomend this distributed (C) service, since there are multiple pathways for communication, the loss of any participant/internet will not prevent communication; other highly recomended p2p e2ee distributed (C) application is Keet. I also recomend Matrix, which is an open network for secure (e2ee) and decentralized (B) communication; to connect to the Matrix federation, you will use a client, one of the most popular is element. You can also use Signal, however this is a centralized (A) service (e2ee), is susceptible to outages or policy/ownership which can change easily, also it needs a cellphone number.
