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.

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.

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.

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.

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.
08/06/2017 - 08/06/2017
ICCUB Seminar – Supermassive black holes as the regulators of star formation in central galaxies
DAM seminar room (724), 7th floor
Studies have shown that feedback from supermassive black holes have profound effects on the gaseous atmospheres of massive galaxies. The consequences of these effects result in dramatic changes with respect to how the baryon cycle works and whether or not new stars are able form from within these galaxies.

ICCUB Seminar – An interferometric journey around massive stars: a decade of amazing results
DAM seminar room (724), 7th floor
Since the construction of modern facilities such as VLTI and CHARA, interferometry has become a key technique to probe massive stars and their often-complex circumstellar environments. In this seminar, I will briefly introduce the basics of this technique and its application to astrophysics.
23/05/2017 - 23/05/2017
ICCUB Seminar – The First Axionic Dark Matter Simulations for the “no-WIMP Era”
Seminar Room 724 (Facultat de Física)
I will describe cosmological simulations of Axion-like Dark Matter, motivated by string theory, providing a well motivated cold dark matter alternative to the standard heavy particle interpretation. Standing waves and other interference effects are predicted within Galaxies that we test with QSO lensing, pulsar timing and via dynamical effects.
