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.

Tension on the Hubble constant: systematic uncertainties or new physics?
Sala Alberto Lobo (ICE building, UAB Campus)
With the recent increase in precision of our cosmological datasets, measurements of ΛCDM model parameter provided by high- and low-redshift observations started to be in tension.

Weak lensing with uncertain redshifts
Seminari DAM (724, ICCUB building, UB Campus)
The cosmological conclusions of weak lensing surveys are very sensitive to the assumed redshift distributions of sources placed in different tomographic bins. In reality, these distributions are not known quantities, so from a Bayesian perspective, they should be treated as random objects, constrained by data.

The (endless) quest for obscured AGN
Seminari DAM (724, ICCUB building, UB Campus)
In the last twenty years, X-ray surveys have revealed that a significant fraction of accretion through cosmic time is obscured. In this talk I will highlight some recent results obtained by combining the strength of deep X-ray observations (as those in the Chandra Deep Field North and South, and COSMOS) with optical/mid-IR information.

Stellar Population of galaxies and their evolution
Sala Alberto Lobo (ICE building, UAB Campus)
In this talk, I will present my research trajectory to the ICE. I will review some of the main observed galaxy properties and relations and how they change across cosmic time.

Inflationary universe in F(R) gravity with antisymmetric tensor fields and their suppression during its evolution
Sala Alberto Lobo (ICE building, UAB Campus)
The intriguing question, why the present scale of the universe is free from any perceptible footprints of rank-2 antisymmetric tensor fields (generally known as Kalb-Ramond fields), is addressed. A quite natural explanation of this issue is given from the angle of higher-curvature gravity, both in four- and five-dimensional spacetime.
