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.

The heart of darkness

Can a molecular cloud beat?

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.

Simpson's paradox in Galactic Archaeology
DAM Seminar (Room 724, ICCUB building, UB Campus)
Galactic Archaeologists use the observed stellar kinematics, chemical abundances, and derived ages as fossil records to recover the chemo-dynamical history of the Milky Way.
CSIC

General relativity and extreme-mass-ratio binaries
Sala Alberto Lobo (ICE building, UAB Campus)
In this talk, I will give a broad and largely non-technical overview of general relativity and strong gravitational two-body systems, from the status of their theoretical modeling to their observation via gravitational waves.

Looking for Partially-Massless Gravity
Pere Pascual (507; ICCUB building, UAB Campus)
I will summarize the status of the search for a unitary theory of partially-massless (PM) spin-two field interacting with Gravity in arbitrary dimensions.
UB

Supervised machine learning for ultracold atoms in speckle disorder
Room 507 (Pere Pascual; ICCUB building, UB Campus)
Due to the availability of big databases, of high-performance computers, and of efficient optimization algorithms, the use of machine learning techniques in the industry and in scientific research is growing at an impressive rate.

Heavy Dynamical Axions
Seminari Pere Pascual (ICCUB Building, Campus UB)
In this talk, I present a model with an enlarged color sector which solves the strong CP problem via new massless fermions. QCD color is unified with another non-Abelian group with a large confinement scale.
