ICCUB SEMINAR – Illuminating the faint Universe
DAM seminar room (724), 7th floor
Only once in a generation is there the opportunity to reveal the basic properties of a new galaxy type for the first time. With the advent of more sensitive instruments in the current large telescopes, an entirely new universe is being revealed, as it had never been seen before.
15/01/2018 - 29/01/2018
ICCUB COURSE – Course on “Scientific Philosophy”
Sala de Graus (aulari). Facultat de Física
The course addresses the fundamental problems of scientific philosophy, that is, philosophy inspired by science. The approach is not historical but based on concrete problems and proposals for solutions to them.
11/12/2017 - 15/12/2017
ICCUB COURSE – Course on “Numerical Relativity”
Room 507 (Pere Pascual), 5th floor
Topics Covered, Preliminary Course Outline:
23/11/2017 - 23/11/2017
ICCUB SEMINAR – New candidate RR Lyrae star streams in the inner Galaxy
Room 507 (Pere Pascual), 5th floor
In this talk we will present our findings of fourteen new candidate RR Lyrae stellar streams in the inner galaxy (4
20/11/2017 - 22/11/2017
ICCUB COURSE – An introduction to Bayesian Statistics through Astronomical Application
V12M (Facultat de Física)
The goal of this course is to provide undergraduate and masters students a first contact with Bayesian Inference. We will introduce basic probability concepts emphasizing the interpretation of probability in the Bayesian framework.
16/11/2017 - 16/11/2017
ICCUB SEMINAR – Lensing convergence in galaxy clustering in LCDM and beyondd
DAM Seminar Room, 7th floor
We study the impact of neglecting lensing magnification in galaxy clustering analyses for future galaxy surveys, considering the ΛCDM model and two extensions: massive neutrinos and modifications of General Relativity. Our study focuses on the biases on the constraints and on the estimation of the cosmological parameters.
30/10/2017 - 30/10/2017
ICCUB SEMINAR – Predicting the radiative display of Type Ia Supernovae: The case for multiple progenitor channels
Room 507 (Pere Pascual), 5th floor
Type Ia supernovae (SNe Ia) are amongst the most energetic stellar explosions. With typical luminosities several billion times that of the Sun, SNe Ia are visible across a large fraction of the observable universe, and enabled the discovery of its accelerated expansion.
27/10/2017 - 27/10/2017
ICCUB SEMINAR – Self-consistent models of our Galaxy in the Gaia era
DAM seminar room (724), 7th floor
I present an approach for constructing self-consistent dynamical models of our Galaxy based on distribution functions (DF) in the action space. The parameters of the DF are adjusted to match observed rotation curve and distribution of stars in the Solar neighborhood, and the gravitational potential is computed from the DF iteratively.
24/10/2017 - 26/10/2017
ICCUB LECTURE – LECTURES ON GRAVITATIONAL DYNAMICS
Room V12M / Room 505
Lectures: Tuesday 24th and Wednesday 25th October, 17:40-19:00 (Room V12M) Lecture 1: Astrophysical introduction to gravitational dynamics. Basic concepts: mean-field regime, two-body relaxation, collective effects, secular evolution. Physical regimes: collisional vs. Collisionless. Overview of gravitational N-body problem, computational challenges. Astrophysical contexts: planetary systems, star clusters, galactic dynamics, cosmological structure formation.
23/10/2017 - 23/10/2017
ICCUB SEMINAR – The Alleged Small-Scale Problems of LambdaCDM
Room 507 (Pere Pascual), 5th floor
The Lambda Cold Dark Matter (LCDM) framework successfully accounts for observational constraints on large (> 1 Mpc) scales, from the clustering of galaxies to the angular dependence of the Cosmic Microwave Background to the structure and matter content of galaxy clusters.
18/10/2017 - 18/10/2017
ICCUB SEMINAR – The formation and dynamics of the first solids in the solar system
Room 507 (Pere Pascual), 5th floor
Calcium-aluminum rich inclusions (CAI) are small metal rich pebbles found inside primitive, thermally unprocessed, meteorites. CAIs are special in the meteoritic inventory. They formed at high temperatures and pressures and are believed to have condensed from a hot metal-rich gas close to the protosun.
19/09/2017 - 19/09/2017
ICCUB SEMINAR – Break-Through Opportunities in Modeling Star and Planet Formation with DISPATCH
Room 507 (Pere Pascual), 5th floor
The new DISPATCH code framework promises great new opportunities in the modeling of star and planet formation – contexts that require extreme ranges of scales to be covered, in order to avoid having to impose arbitrary initial and boundary conditions.
10/07/2017 - 14/07/2017
Second Barcelona Techno Week – Course on nanosatellites
Institute of Cosmos Sciences (Physics Faculty UB)
Barcelona Techno weeks are a series of meeting point events between academia and industry, organised around a technological topic of interest for both worlds.
04/07/2017 - 04/07/2017
Tidal disruption events and the peculiar case of iPTF16fnl
DAM seminar room (724), 7th floor
Tidal disruption events are a power supply for short duration accretion episodes in SMBHs. For lower mass SMBHs, the returning timescales of the bound stellar debris is expected to be faster than for larger SMBHs, leading to shorter flare timescales and high accretion rates.
22/06/2017 - 22/06/2017
ICCUB SEMINAR – The Magellanic Inter-Cloud Project: First spectroscopic evidence of a dwarf stripping a dwarf
DAM seminar room (724), 7th floor
The Magellanic Bridge (MB) is a gaseous stream that links the Large (LMC) and Small (SMC) Magellanic Clouds. Current simulations suggest that the MB forms from a recent interaction between the Clouds.
