Matérias sugeridas na graduação da USP para futuros astrofísicos

Frequentemente me perguntam quais as matérias na graduação da USP eu sugeriria para estudantes de física e de outros cursos que desejam ter uma base sólida em astrofísica.

Bem, eu primeiro lugar eu recomendo fazer o curso de graduação em astronomia que oferecemos no IAG USP. Neste curso, os estudantes recebem uma formação sólida para entender os processos físicos por trás do universo, assim como aprendem as ferramentas computacionais necessárias para se fazer descobertas.

Caso você esteja cursando física, ainda assim é possível ter uma formação sólida que forneça uma compreensão de astrofísica mais profunda. Eis a lista de matérias que considero importantes. A minha ênfase é numa sólida formação nos processos físicos por trás do cosmos, e em matemática—que é a linguagem do universo:

  1. Mecânica II
  2. Relatividade geral e aplicações astrofísicas
  3. Introdução à cosmologia
  4. Métodos computacionais em astronomia
  5. Mecânica dos fluidos
  6. Introdução à física de plasmas e fusão nuclear
  7. Eletromagnetismo II
  8. Física matemática II
  9. Introdução à física de partículas elementares

Pode ser difícil encaixar todas estas disciplinas no tempo disponível no curso, por isto tentei ordena-las de acordo com a sua “relevância astrofísica”. Para mais informações sobre estas matérias, consulte o Júpiter Web.

Palestra: A nova era de ouro dos buracos negros

Na Quarta-feira, dia 23 de Setembro às 18:00, darei a palestra de divulgação científica intitulada “A Nova Era de Ouro dos Buracos Negros” no evento Convite à Física, organizado pelo IF USP. Seguem as informações abaixo.

A nova era de ouro dos buracos negros

Os anos 60 foram os anos dourados da pesquisa teórica sobre buracos negros, onde nomes como Thorne, Hawking, Wheeler e Zel’dovich elevaram a nossa compreensão física destes estranhos astros a um outro patamar. Neste convite à física, argumentarei que entramos em 2015 numa segunda e empolgante era de ouro da pesquisa em buracos negros, impulsionada desta vez por avanços empíricos. Quais são as principais descobertas da nova astronomia de buracos negros? E o que vem pela frente?

Welcome Fabio: Future master of Sgr A*

Hello everyone!

My name is Fabio Cafardo and I just started my PhD in Astrophysics at IAG-USP under the supervision of Prof. Rodrigo Nemmen. I’m really happy and motivated by this new challenge in my life.

Astronomy has always been one of my passions. But, before getting my Astrophysics degree, I worked 10 years as a Business Administrator. This experience proved to me that it is very important to work with something which you really like. That’s what I am doing now!

The topic of my research project is the high-energy emission of the supermassive black hole in the center of Our Galaxy, called Sagittarius A*. It is a fascinating topic and I really hope to provide new insights into the high energy processes occurring there.

Welcome aboard, Fabio! We are happy you switched gears and are working with us.

Welcome, Ivan

This semester, we are welcoming a new member to the group: Ivan Almeida. Ivan just graduated with stellar grades at Physics USP and will begin his work as a grad student in the group. Below are a few words from him:

Hi all, my name is Ivan Carlos de Almeida, and I’m beginning my masters degree at IAG-USP under the supervision of professor Rodrigo Nemmen. I’m a physicist recently graduated at IF-USP.

While I were an undergrad student I’ve entered the “Black Hole group” as a student of “Iniciação Científica”. This was my first effective contact with astrophysics and it was really interesting!

Since childhood I’m curious about the night sky, stars and all the cosmos. Some years later I have developed interest in General Relativity. So Black Hole physics attracted me greatly.

In the current project I’ll do HD and MHD simulations of accretion around black holes. I’ll investigate the existence of winds and if these winds provide efficient feedback inside the galaxy.

Ivan was quite successful during his undergraduate research project: we are anticipating 2 papers resulting from his work. He got the prestigious FAPESP scholarship that will fund his graduate studies. A very small fraction of students obtain this scholarship.

Welcome aboard, Ivan!

Postdoctoral opportunity at our Black Hole Group

We have one or more postdoctoral positions available at our Black Hole Group. If you are interested in black hole (astro)physics (including theory/numerical simulations), AGNs and/or gamma-ray astronomy, you are welcome to apply for one of the positions.

More information about the position can be found in this detailed announcement or in the AAS Job Register (shorter) ad that will be published on Feb 1st. The deadline for applications is March 1st 2017.

One clarification though: this is a pre-application. The selected candidate(s) will be sponsored for a postdoctoral fellowship application to the Sao Paulo funding agency FAPESP. If approved, the position will be funded for two years with the possibility of extension for a third year contingent on performance. The salary is generous for Brazilian standards (it is the best paying postdoc salary in the country) and includes research/travel budget and relocation costs.

 

Congratulations to Raniere Menezes for his MsC degree

This is a late post, but I would like to congratulate Raniere Menezes who obtained his MsC on September. Raniere is the first graduate student who got his degree in the Black Hole Group. His master’s dissertation was on analyzing the gamma-ray variability of nearby AGNs observed with Fermi LAT.

Raniere’s work was very successful: we are writing a paper reporting the results of his analysis.  Stay tuned!

Welcome to IAG, Henrique

Let’s give a warm welcome to Henrique Gubolin, my new graduate student. Let’s hear from Henrique himself:

Hi! I’m Henrique Gubolin Torres, and I’m starting my masters degree under the supervision of Rodrigo Nemmen; I just graduated in physics at IF-USP and I already worked with galaxy clusters and simulations before.

In this new project, I’ll be doing black hole simulations with the help of some well known magnetohydrodynamic codes, of course. We will simulate gas around a non-spinning black hole (Schwarzschild) using a semi-Newtonian approach and Magnetohydrodynamic (MHD). I’m looking forward to this project and to my new graduate student life, so… here we go!
