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.

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.

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.

Outflows from young stars
Sala Alberto Lobo (ICE builduing, UAB 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 a turbulent feedback that can be of relevance in the Galactic energy budget.

Energetic Particle Environment activities at ESA’s Space Environment and Effects section
Seminar DAM (724, ICCUB building, UB Campus)
Solar energetic particles including protons, alpha particles, heavier ions, and electrons are accelerated from the solar corona and in interplanetary space by shocks driven by coronal mass ejections.

Non-perturbative techniques in strongly coupled field theories
Room 507 (Pere Pascual, ICCUB Building, UB Campus)
Non-perturbative techniques are needed to study strongly coupled systems. One powerful approach is the n-particle irreducible effective action. The method provides a systematic expansion for which the truncation occurs at the level of the action.

The discovery of a comet fragment inside a meteorite provides clues about water delivery
Sala Alberto Lobo (ICE building, Campus UAB)
In our Meteorite Microscopy Clean Room we have discovered the first cometary fragment found inside a meteorite, precisely in the CR2 carbonaceous chondrite LaPaz 02342.

The large D membrane paradigm for general four-derivative theory of gravity in the presence of a cosmological constant
Aula 507 (Pere Pascual), ICCUB Building, Campus UB
The large D membrane paradigm defines an equivalence between black hole dynamics and the dynamics of a membrane propagating in a spacetime to which the black hole asymptotes to.

EoS in neutron stars - recent results on cooling and tidal deformabilities
Sala Alberto Lobo
We present our recent results on cooling and tidal deformabilities of neutron stars using a recently developed hadronic equation-of-state (EoS) for the neutron star interior.

White dwarfs in the Gaia era
Sala Alberto Lobo
The vast majority of stars will end, or have ended, their lives in the form of a white dwarf. These objects have the average size of the Earth; however, they can be more massive than the Sun. This makes white dwarfs to be extremely dense and to have exceptional properties. In this talk, we will study the physical characteristics of these exotic objects and we will see how the data provided by the Gaia satellite is helping us to significantly increase our understanding of white dwarfs.

Does size matter? The case of the HH80-81 disk
Sala Alberto Lobo (ICE building, Campus UAB)
Understanding how high-mass stars form and evolve is one of the hot topics in astrophysics, due to the high impact that these objects have in the life of a galaxy.

Chemical Complexity in Space and Earth Induced by Solid State Surfaces. Investigations by means of Quantum Chemistry.
Sala Alberto Lobo
Our universe is molecularly rich [1-3], comprising from the most essential molecules (such as H2, H2O and NH3), passing through complex organic molecules (namely, COMs, molecules between 6–13 atoms where at least one is C rendering its organic character), reaching more evolved complex organic compounds, in which in some cases are of biological relevance, such as amino acids, nucleobases and sugars.

"The Glass Universe" Women Pioneers of Astronomy
Barcelona, CCCB
As part of the International Women’s Day programme, the writer and scientist Dava Sobel will speak about the main characters of her book The Glass Universe: How the Ladies at Harvard Observatory Took the Measure of the Stars (in Spanish, El universo de cristal, Capitán Swing, 2017) and the role of women in science.
