Entrevista no Jornal Record News, sobre a Sonda Rosetta e o pouso do robô Philae no cometa 67P

Na Quarta-feira da semana passada, 12 de Novembro, fui entrevistado no Jornal da Record News do Canal Record News, pelo apresentador Heródoto Barbeiro. Falei sobre o feito histórico da Sonda Rosetta, e do pouso do robô Philae no cometa 67P.

O vídeo da entrevista, em duas partes consta nos links abaixo:

Gostei da maneira como o Heródoto conduziu a entrevista.


Inauguration of ASTRI SST-2M telescope, Cherenkov Telescope Array

I had the pleasure this week to attend the inauguration of the ASTRI SST-2M telescope at Serra La Nave, Catania. This telescope is a prototype for the mini-array telescopes that will be part of the Cherenkov Telescope Array (CTA). CTA is the future of ground-based gamma-ray astronomy. The mini-array in particular will observe the universe at energies >10 TeV. For comparison, a 10 TeV photon has 1013 times more energy than an optical photon. CTA will observe the high-energy universe in a complementary energy range to the amazing Fermi LAT.


Congrats to the newest PhD of IAG, Dr. Rocha da Silva

Congratulations to the newest PhD of our department, Dr. Gustavo Rocha da Silva! This week, Dr. Rocha da Silva successfully defended his thesis on MHD simulations of relativistic jets from gamma-ray bursts (GRBs), and demonstrated the importance of relativistic MHD in understanding the physics of GRB afterglows and the amplification of magnetic fields in the environment of such objects.

I was part of his PhD thesis committee — my first time in such a committee — and I enjoyed it very much.

COSPAR Scientific Assembly 2014, Moscow

I will attend the 42th COSPAR Scientific Assembly in Moscow, Russia. I am excited to visit Russia for the first time!

I will give two talks: one review talk about the role of relativistic jets in unified models of active galactic nuclei and current challenges, at the “challenges in unified models of AGN” meeting; the second talk is about this recently submitted paper at the “outflows and accretion from white dwarfs to supermassive black holes” event. I am also excited to hear news about the possible G2 object accretion by our Galactic Center at the “new broadband perspectives on the Galactic Center black hole and its environment” meeting. Here is the list of astrophysics meetings.

For those attending the conference: see you in Mother Russia!

Outreach talk: 17 Ways a Black Hole Can Kill You

I am giving an outreach talk on this Thursday, May 29th, as part of  the “Astronomy for Lunch” (Astronomia ao Meio Dia) outreach series at IAG USP about “17 ways a black hole can kill you”.

Vou apresentar um seminário de divulgação científica no evento “Astronomia ao meio dia” no IAG USP, intitulado “17 maneiras de ser morto(a) por um buraco negro”. Venha conferir nesta Quinta-feira, 29 de Maio, no Auditório do IAG.

Top Ten Space Stories of the Year in Astronomy Magazine

One of my papers has been highlighted in the top ten space stories of 2013 in the January 2014 issue of the Astronomy Magazine!

My research is among other “high-impact” events of 2013 such as: Curiosity finding a once-habitable environment on Mars, the Planck satellite measuring the most detailed yet map of the cosmic microwave background and the once-in-a-century meteoroid that exploded over Chelyabinsk in Russia and others.
