Dark side of the seesaw

I will explore the idea of connecting the dark matter sector with a sector of the Standard Model (SM), namely the neutrino sector. To do this, I consider the extension of the SM with right-handed (gauge singlet) neutrinos, which will lead to a type-I seesaw mechanism. Then I also add a fermion (another gauge singlet) dark matter candidate.

Greybody factors are frequency dependent quantities that measure the deviation from the perfect black body spectrum of Hawking radiation, and they provide us with valuable information about the near horizon structure of black holes. In
addition, when black holes are perturbed the geometry of spacetime undergoes dumbed oscillations.

RISE coordinator's day 2018

A team from Aveiro University composed by Tatiana Costa (Aveiro Research Support Office), Nikolai Sobolev and Carlos Herdeiro (both RISE projects coordinator from the Aveiro Physics Department) was present in the RISE coordinator's day at the head of REA (Research Executive Agency) in Brussels, in 18-19 January 2018. The photo shows the RISE coordinators of the Math/Physics panel with REA staff, including Project Officer Amanda Jane Ozin-Hofsaess and the Head of Unit Fredrik Olsson Hector.

Ema Valente is now a Master

Ema Valente successfully finished her Physics M.Sc. at Aveiro University, on December 20th 2017, by defending a thesis with title "A simple model of exotic compact objects: interaction with a scalar field". This thesis was supervised by Gr@v researcher C. Herdeiro and examined by Prof. Luis Crispino, from the U. Federal do Pará, Brazil. Well done Ema!
