Many theories beyond the Standard Model (SM) have been proposed to address several of the SM shortcomings, such as explaining why the Higgs boson is so light, the origin of neutrino masses, or the observed pattern of masses and mixing angles in the quark and lepton sectors. Many of these beyond-the-SM extensions predict new particles or interactions directly accessible at the LHC. This talk...
Structures in the universe can be formed because of small inhomogeneities at a very early time. These inhomogeneities originate from quantum fluctuations stretched by cosmic inflation.

Recent cosmological analyses combining Planck CMB data with baryon acoustic oscillation (BAO) measurements from the DESI collaboration have revealed a statistically significant preference for evolving dark energy (DE) models over the standard cosmological constant. In particular, fits using the Chevallier–Polarski–Linder (CPL) parameterization indicate a $\sim\!4\sigma$ deviation from a...
We explore flavored resonant leptogenesis embedded in a neutrinophilic 2HDM. The mass pattern of the right-handed neutrinos~(RHNs) is generated by invoking a softly broken U(1) lepton family number difference symmetry. Such a symmetry features two degenerate heavy RHNs and a massless one. The soft breaking then generates a small splitting between the two heavier one, while also generating mass...
Gamma-ray bursts (GRBs) are typically observed as brief flashes of MeV radiation. Short-duration GRBs (< 2 s) are commonly associated with neutron star mergers, making them prime multi-messenger sources with gravitational waves. Long-duration GRBs (~20 s), on the other hand, are linked to certain classes of collapsars. Despite this broad dichotomy, recent discoveries have revealed puzzling...

The statistical properties of the CMB anisotropies, reflecting the curvature inhomogeneities in the early Universe, are very well accounted for by assuming that they emerged from amplified vacuum fluctuations.
Being the result of a genuine quantum process, it is natural to wonder which properties of these primordial inhomogeneities are quantum, and which, if any, persisted until their...
Although the cosmic microwave background (CMB) is assumed to be only linearly polarized due to the Thomson scattering, some exotic theories predict the generation of circular polarization in the CMB during its propagation. E.g., Faraday conversion due to the supernovae remnants of first stars[1], the scattering by cosmic neutrino background[2], and Lorentz violation[3]. Thus, the circular...
Observationally, we only know that dark matter (DM) interacts gravitationally.

This scenario has been studied extensively in the context...
Grand Unified Theories (GUTs) viewed as the extension of Standard Model (SM) are proposed and unify the strong, weak, and electromagnetic interactions at the order of $10^{15}$-$10^{16}$ GeV which is unreachable by accelerators.

The thermodynamics of black holes inspired the concept of black hole entropy, linking gravity and thermodynamics. When applied to cosmology, this leads to the standard Friedmann equations, which face challenges in explaining the universe’s evolution. Modified entropies have been proposed to resolve these issues.

The search for neutrinoless double beta (0$\nu\beta\beta$) decay is considered as the most promising way to prove the Majorana nature of neutrinos as well as to give an indication on the mass hierarchy and on the absolute mass scale. The discovery of 0$\nu\beta\beta$ decay would moreover open the way for theories predicting the observed matter anti-matter asymmetry of the Universe being a...
The James Webb Space Telescope (JWST) has opened up new vistas to the very distant universe hitherto inaccessible.

Using high-resolution ultraviolet spectra of Fe V in the white dwarf G191-B2B from HST/STIS, combined with precise laboratory data, we constrain the time variation of...
Determining the absolute mass of neutrinos remains a major challenge in cosmology and particle physics. Recent DESI DR1/DR2 results suggest potential deviations from the standard ΛCDM model and indicate that conventional two-point statistics may be insufficient to robustly detect Mν – sparking controversial hints of a negative neutrino mass. To overcome these limitations, we introduce robust,...

Star formation is a continuous cycle of interchange of matter and energy between stars and the interstellar medium of galaxies. As a result of a complex interplay between gravitational, kinetic, and magnetic energies, shock compressions, and heating/cooling processes, the matter is assembled from the diffuse, large-scales to the dense, small-scales, where gravity prevails over the pressure...
