Especial Christmas Seminar: The 'Climate Emergency': scientific basis, impacts and possible solutions to the first planetary human problem
Sala Alberto Lobo (ICE building, UAB Campus)
Humanity has been causing environmental problems forever and has often resolved them with great success. But in the past, these were problems faced by local populations, which were able to coordinate their activities in order to resolve them locally.

ELGAR: The European Laboratory for Gravitation and Atom-interferometric Research
Sala Alberto Lobo (ICE building, UAB Campus)
After the inauguration of Gravitational Wave Astronomy with the first direct detection of Gravitational Waves from a binary black hole coalescence by the Laser Interferometer Gravitational-wave Observatory (LIGO), the race to cover the most relevant parts of the Gravitational-wave spectrum is currently at full speed.

Black Hole in Globular Clusters
SalaAlberto Lobo (ICE building, UAB Campus)
Globular clusters (GCs) are the outcome of the earliest phases of star and galaxy formation in the Universe. Their high densities foster the formation and hardening of binary black holes (BHs) that can merge via gravitational wave in-spiral.

Gravitational Anomalies in a string-inspired "Running Vacuum Universe'': dynamical inflation, matter-antimatter asymmetry and axion dark matter
Aula Pere Pascual (507, ICCUB building, UB Campus)
I discuss a string-inspired cosmological model, in which primordial gravitational waves induce condensates of gravitational-anomaly terms, which are in turn responsible for inflation, and the generation of a (massless) gravitational axion background that breaks spontaneously Lorentz (and CPT) symmetry and remains undiluted at the end of inflation.

Unprecedented detection of a GRB up to TeV energies unveils a new spectral component
Sala de Graus Eduard Fontserè (ICCUB building, UB Campus)
The hunt for Gamma-Ray-Bursts (GRBs) at very high energies (VHE) started more than 20 years ago. A hint of emission was already claimed by Milagrito from the observations of GRB 970417. On 19 January 2019, the Major Atmospheric Gamma Imaging Cherenkov (MAGIC) clearly detected GRB 190114C above 0.2 TeV.

Magnetic environment and experiments on-board LISA Pathfinder
Sala Alberto Lobo (ICE building, UAB Campus)
The differential acceleration measurement between two free-falling test masses on-board LISA Pathfinder is limited in the low-frequency regime by force noise applied to the test masses.

Sponsor a carolingi
Sala Alberto Lobo (ICE building, UAB Campus)
Have you ever found a skeleton in your backyard? Have you ever found four of them? In this presentation, I will talk about how four tombs helped me to learn a little bit of history, and how it is to have an archeological site at home. Based on a real story.

COSMIC DANCE: A comprehensive census of nearby star forming regions
Seminari DAM (724, ICCUB building, UB Campus)
The study of star formation is extremely challenging due to the lack of complete and clean samples of young, nearby clusters, and star-forming regions. The recent Gaia DR2 catalogue complemented with the deep, ground-based COSMIC DANCE catalogue offers a new database of unprecedented accuracy to revisit the membership of clusters and star-forming regions.

Star formation in the Alhambra mosaics. A geometrical divertimento.
DAM Seminar (724, ICCUB building, UB Campus)
This is not a talk on astrophysics of star formation, but on geometry, on how the central stars of the Arabic mosaics of the Alhambra are created.

Primordial non-gaussianities or relativistic effects in Large Scale Structures?
DAM Seminar (724, ICCUB building, UB Campus)
In this talk, I will discuss some aspects of non-linear structure formation. The calculation of the bispectrum usually involves linear physics on large scales and non-linear (but Newtonian) physics on small scales. However, in the squeezed limit, the bispectrum (unlike the power spectrum) couples large scales with small scales.

Star formation, polarization, and magnetic fields in the ALMA era
Sala Alberto Lobo (ICE building, UAB Campus)
New ALMA polarization observations continue to both expand and confound our understanding of the role played by the magnetic field in low-mass star formation. The sample of very young, Class 0 protostellar sources observed with high resolution and high sensitivity with ALMA is now large enough that we are beginning to see the same surprising features in multiple sources.

Nuclear structure connected to neutrino physics and dark matter searches
Aula 507 (Pere Pascual, ICCUB building, UB Campus)
Atomic nuclei are sensitive to strong, weak, and electromagnetic interactions. In addition, nuclei are ideal laboratories to search for physics beyond the Standard Model, in processes such as neutrinoless double-beta decay, the direct detection of dark matter, or coherent neutrino-nucleus scattering. All these are governed by nuclear matrix elements (NMEs) that depend on the structure of the nuclei involved.

Gauge/gravity duality at the core
Aula 507 (Pere Pascual, ICCUB building, UB Campus)
Matter in the interior of neutron stars can reach densities several times larger than that of atomic nuclei. Properties of matter at such high densities can be constrained from astrophysical observations and gravitational-wave signals produced by binary mergers.

Recent results from CARMENES
Sala Alberto Lobo (ICE building, UAB Campus)
The CARMENES spectrograph is surveying around 300 M-dwarf stars to look for exoplanets. About 20 exoplanets have already been announced, and a number of candidates are still under analysis.

Inferring the dynamical growth of structures at high-redshift
Seminar DAM (742, ICCUB building, UB Campus)
While the standard model of cosmology fits most cosmological observations to extraordinary accuracy, some tensions between the model and observations seem to persist despite the increasing quality of data.
