Global High-Precision Phase-Delay Astrometry at mm-Wavelengths: State-of-the-Art and Technical Limits
DAM Seminar (724, ICCUB building, UB Campus)
Wide-angle high-precision differential phase-delay astrometry with VLBI at 7mm wavelength has been successfully demonstrated with state-of-the-art observations and analysis of a complete sample of 13 radio sources (Quasars and BL Lacs).

The star formation history in the solar neighborhood as told by massive white dwarfs
Sala Alberto Lobo (ICE building, UAB Campus)
White dwarfs are the remnants of low and intermediate mass stars. Because of electron degeneracy, their evolution is just a simple gravothermal process of cooling. Recently, thanks to Gaia data, it has been possible to construct the luminosity function of massive (0.9 < M/Msun < 1.1) white dwarfs in the solar neighborhood (d < 100 pc).

The equation of state and deconfinement in QCD
Pere Pascual (507, ICCUB building, UB Campus)
The low-energy phase of the theory of strong interactions, Quantum Chromodynamics (QCD), features a remarkable property of confinement - the spectrum contains composite, color-neutral states, while states with non-zero color charge are not observed.

Multibaryon physics directly from quarks and gluons
Aula 507 (Pere Pascual, ICCUB building, UB Campus)
The idea of studying nuclear physics directly from the degrees of freedom of the Standard Model, quarks and gluons, has been long sought in the physics community. During the last few decades, the numerical method called lattice QCD has been able to compute the simplest quantities, such as the hadron masses, directly from first principles.

Simulations on reverberating and superefficient pulsar wind nebulae
Sala Alberto Lobo (ICE building, UAB Campus)
Pulsar wind nebulae (PWNe) experience significant evolution in reverberation phase, when the reverse shock created by the supernova explosion travels back towards the pulsar, compressing the wind bubble.

Time-crystal ground state and production of gravitational waves from QCD phase transition
Aula 507 (Pere Pascual, ICCUB building, UB Campus)
We propose a novel mechanism for the production of gravitational waves in the early Universe that originates from the relaxation processes induced by the QCD phase transition.

Red giants, chemical clocks of the Milky Way
Seminari DAM (724, ICCUB building, UB Campus)
A broad effort is ongoing with large spectroscopic surveys such as APOGEE, Gaia-ESO, GALAH, LAMOST from which stellar parameters, radial velocities and detailed chemical abundances can be measured for CoRoT, Kepler, and K2 targets.

Public communication of science. A portal to the public: IATE & OAC experience
Sala Alberto Lobo (ICE building, UAB Campus)
Science communication is a growing area of practice and research. During the past two decades, the number of activities, courses, and practitioners has steadily increased. But why is important to do Science Communication?

New Fayet-Iliopoulos terms in supergravity for supersymmetry breaking by anti-D3 branes.
Aula 507 (Pere Pascual) (ICCUB building, UB Campus)
A review will be given on supersymmetry breaking and some aspects of non-linear supersymmetry. A new type of N=1 Fayet-Iliopoulos (FI) terms in supergravity will be discussed.

3D imaging of the emission from the inner ejecta of SN1987A
Seminari DAM (724, ICCUB building, UB Campus)
Supernova SN1987A in the Large Magellanic Cloud offers an unprecedented opportunity to research on fundamental issues of supernova explosions: dust and molecule formation, interaction with the circumstellar medium, particle acceleration, pulsar formation, etc. Since 2011, instruments like ALMA have been fundamental for such endeavour.

Shedding light upon our Galaxy and its past with Gaia
Seminari DAM (724) (ICCUB building, UB Campus)
As promised, the excellent precision and large amount of data delivered by the Gaia satellite have allowed us to progress outstandingly on the studies of our Galaxy during this first year of scientific harvest after the Data Release 2.

Primordial black holes’ dark dresses: Roads towards a discovery and possible implications
Seminari DAM (724) (ICCUB building, UB Campus)
The birth of gravitational wave astronomy has been a major recent breakthrough in physics. The recent discovery of gravitational wave signals from merger events of massive binary-black-hole (BBH) systems have prompted a renewed debate in the scientific community about the existence of primordial black holes of O(1-100) solar masses.

Particle acceleration in protostellar jets: an observational approach
Sala Alberto Lobo (ICE building, UAB Campus)
Deeply embedded protostellar jets are well known to be dominated by the emission of thermal electrons. Interestingly, in the last decades, negative spectral indices have been detected at centimeter wavelengths in some protostellar jets, indicating the presence of a non-thermal component.

Outflows from young stars
Seminari DAM (ICCUB building, UB Campus)
Outflows are ubiquitous in star-forming regions. They are associated with accretion events and trace the rich chemistry produced by shocks and heating surrounding protostars. Protostellar outflows yield turbulent feedback that can be of relevance in the Galactic energy budget.
