Connecting to ICE using VPN


Start: 12:30h
Speaker: Josep Guerrero (Institut de Ciències de l'Espai (CSIC-IEEC))
Place: Sala de Conferències Alberto Lobo (ICE, Campus UAB)

This talk will be divided in two pats: a general one in which I'll explain what is a VPN, what problems it solves and what advantages it has over other connection methods, and a more specific one that will describe how the ICE VPN works, how to activate it and how to write a correct configuration…

The amazing world of exoplanets


Start: 12:30h
Speaker: Ignasi Ribas Canudas (Institut de Ciències de l'Espai (CSIC-IEEC))

In less than two decades from the publication of the first discovery, exoplanet science has experienced a true revolution.

In less than two decades from the publication of the first discovery, exoplanet science has experienced a true revolution. Today, we know about 2000 confirmed exoplanets and, for some of them, we have managed to observe the spectroscopic signatures of their atmospheric constituents. Even in the relatively small parameter space that we have investigated thus far, Nature has revealed an unsuspected variety of planetary systems, indicating that the Solar System is not the paradigm. And exoplanet science continues to teem with new ground-based planet search projects and dedicated space missions. In this talk I will review the current status of exoplanet research in terms of the most relevant results and discuss the expected future surveys and facilities, focusing on those in which our group at ICE actively participates.

Why is the Universe Accelerating?


Start: 13:00h
Speaker: Enrique Gaztañaga
Place: Luis Lobo Seminar Room - ICE building (ICE - Campus UAB)

We know the universe is speeding up. But, why is it doing so and why is this important? I will review these questions and explain how we are making cosmic maps which are ever larger and more precise.

On cosmology, infinities, and zeta functions


Start: 12:30h
Speaker: Emilio Elizalde
Place: Sala de Conferencies Alberto Lobo (ICE Building)

What drives the acceleration of the Universe expansion? Dark energy, of course, but what is it? It could well be the ``cosmological constant’’, quantum fluctuations of the vacuum energy. Beautiful, albeit rather non-trivial mathematics, involving the zeta function of pseudo-differential operators…

What drives the acceleration of the Universe expansion? Dark energy, of course, but what is it? It could well be the ``cosmological constant’’, quantum fluctuations of the vacuum energy. Beautiful, albeit rather non-trivial mathematics, involving the zeta function of pseudo-differential operators and the proper definition of traces and determinants, are key in answering this question.

Magnetars life cycle: birth, evolution and death


Start: 12:30h
Speaker: Nanda Rea
Place: ICE seminar room

Magnetars are the strongest magnets we know of, and show themselves via powerful X/gamma-ray steady and flaring emission. The energetics of such flares in our Galaxy second only the supernova explosions. In this talk I will first review the observational characteristics of these highly magnetic pulsars,…

Speaker: Nanda Rea
Place: ICE seminar room

Magnetars are the strongest magnets we know of, and show
themselves via powerful X/gamma-ray steady and flaring emission. The
energetics of such flares in our Galaxy second only the supernova
explosions. In this talk I will first review the observational
characteristics of these highly magnetic pulsars, and some recent
discoveries in the field. Subsequently, I will present what we
currently know about their life-cycle, through detailed simulations of
neutron star magneto-thermal evolution and pulsar population
synthesis. I will then finish with some considerations on how the
study of the Galactic population of magnetars might constrain their
possible connection with Gamma Ray Bursts.
