Nuclear activity and star formation in local Luminous Infrared Galaxies
Sala Alberto Lobo (ICE building, UAB Campus)
Luminous infrared galaxies (LIRGs) dominate the cosmic infrared background, and hence their study is crucial to understand galaxy formation and evolution. Furthermore, their extreme environments make them ideal laboratories to probe both star formation, nuclear activity, and the interplay between both phenomena.

Highly Magnified Cosmological Sources in Galaxy Cluster Lenses
DAM Seminar (724, ICCUB building, UB Campus)
Individual luminous stars or compact star-forming complexes in distant galaxies have been observed by the Hubble Space Telescope in the field of strong lensing massive galaxy clusters. These sources are fortuitously located in the proximity of the lensing caustic and are tremendously magnified by factors in the hundreds or larger.

Electromagnetic counterpart of gravitational wave events
Sala Alberto Lobo (ICE building, UAB Campus)
In the last few years, the gravitational wave (GW) interferometers LIGO and Virgo proved their ability to detect compact mergers and, with the spectacular case of GW 170817. Thanks to them, it is clear that there is a lot to learn from the prompt identification of the electromagnetic counterpart of the GW trigger.

Revealing the structure of the Milky Way via parallax observations of maser sources
DAM Seminar (724, ICCUB building, UB Campus)
Edwin Hubble showed in 1926 that galaxies can be classified into three groups depending on their shape: ellipticals, spirals and irregulars. We know that our own Galaxy has a spiral shape. However, the details of the galactic structure like the number of spiral arms or their exact location are still under debate. In the first part of this talk, I will present recent efforts to unveil the structure of our Milky Way, a complicated endeavour due to our position in the Galaxy.

Corpuscular scaling relations in bootstrapped Newtonian gravity
DAM seminar room (724, ICCUB building, UB Campus)
The corpuscolar model describes black holes as condensates of a large number of gravitons at the critical point. Therefore, self-gravitating systems are depicted as purely quantum states with no central singularity, marking a clear departure from the usual semi-classical picture of quantum field theory on curved (classical) backgrounds.

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.

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.
10/01/2020 - 00/00/0000
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).

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.
