Gravitational Wave Events: Detection and Present Status
DAM Seminar (724, ICCUB building, UAB Campus)
Chirping gravitational wave signals from compact binary Coalescence were detected for the first time during LIGO/Virgo O1 and O2 observing runs. The majority of the events reported thus far came from binary systems of fairly heavy stellar mass black holes located at cosmological distances.

STARS: Telescope and space mission scheduling towards a multi-observatory framework
Sala Alberto Lobo (ICE building, UAB Campus)
Efficient scheduling of astronomical observatories and space missions is a challenge with an increasing complexity as the observation strategies are becoming more sophisticated and operational costs are higher. Astronomical surveys require a huge number of observations, implying the need to use efficient schedulers to fulfill and optimize specific constraints.

A novel approach to diffusing the black hole information paradox
Aula 507 (Pere Pascual, ICCUB building, UB Campus)
We will briefly review the issue of "information loss" during the Hawking evaporation of a black hole, and argue that the quantum dynamical reduction theories, which have been developed to address the measurement problem in quantum mechanics, possess the elements to diffuse the “paradox” at the qualitative and at the quantitative level, leading to what seems to be an overall coherent picture.

White dwarfs as Advanced Physics laboratories: the axion case
Sala Alberto Lobo (ICE building, UAB Campus)
The shape of the luminosity function of white dwarfs (WDLF) is sensitive to the characteristic cooling time and, therefore, it can be used to test the existence of additional sources or sinks of energy such as those predicted by alternative physical theories.

Global Hydrogen Cosmology Data Analysis for Rigorously Separating the Signal from Systematics
Sala Alberto Lobo (ICE building, UAB Campus)
I will discuss our data analysis for sky-averaged 21-cm observations and the status of the experiments for which we are currently developing specific applications of this pipeline, the ground-based Cosmic Twilight Polarimeter (CTP) and the space-based Dark Ages Polarimeter PathfindER (DAPPER).

Simulations at the Dwarf Scale: From Violent Dwarfs at Cosmic Dawn and Cosmic Noon to Quiet Discs today
Seminar DAM (742, ICCUB building, UB Campus)
Dwarf galaxies with stellar masses of 109 Msun can be explored at high and low redshifts and they give a glimpse of the different conditions of galaxy formation at different epochs.

Induced gravitational waves in general backgrounds
Aula 507 (Pere Pascual, ICCUB building, UB Campus)
Gravitational waves are unavoidably generated at second order in cosmological perturbation theory. In some cases, such induced gravitational waves might be observable by future space-based gravitational waves detectors.

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.
