Abstract: In the latest decades, the approaches towards investigating the nature of the dark matter component of the Universe have been marked by prejudices, mostly in connection to: A natural embedding of dark matter into an extension to the Standard Model of particle physics, possibly as a byproduct within models addressing some shortcoming of the Standard Model; A natural mechanism to...

This talk will detail the experimental status of the cosmological standard model. It will cover the recent joint analyses from the Pantheon+ & SH0ES collaborations and that tell two important stories. The Pantheon+ supernova constraints of cosmic acceleration are the current best measurement of the dominant energy density components of the universe and provide strong constraints on potential...

In this talk I will give an overview of the status of the Standard LCDM model, from the perspective of a theoretical cosmologist. After a brief overview of the model itself and its fundamental pillars and assumption, I will briefly describe a selection of the very large number of alternatives proposed. Returning to LCDM, this is based on General Relativity (GR), but when it comes to study...

The phenomenon of the Dark Matter baffles the researchers: the underlying dark particle has escaped so far the detection and its astrophysical role appears complex and unexpectedly related with that of the Standard Model (luminous) particles. We propose that, in order to act efficiently, alongside with abandoning the current ΛCDM scenario, we need also to shift the Paradigm from which such...

At such level of accuracy, a fully general relativistic analysis of photon trajectories from the observational data back to the space-time origin of the emitting astronomical object is mandatory. This necessarily implies the dismissal of Newtonian straight lines and... -

Euclid is a space mission aimed at addressing the key questions of modern cosmology. After a long process started in 2007 in the framework of the ESA Cosmic Vision 2015-2025, it was successfully launched in 2023. Euclid will shed light on the nature of dark energy, the properties of dark matter and its relations with baryonic matter, the mass of neutrino and will test modified gravity on...

The QCD axion offers a compelling solution to the strong CP problem and a well-motivated dark matter candidate, inspiring several ultra-sensitive experiments probing light and weakly-coupled dark sectors. After reviewing the theoretical framework for dark matter axions, I will focus on recent developments in axion model building suggesting that the QCD axion parameter space is much larger than...

Axions and axion-like particles are promising particle candidates to explain cold dark matter. These particles could be detected through their feeble interaction with photons, which could lead to observable signatures in a variety of astrophysical observations. On the one hand, photons and axions produced in astrophysical sources could oscillate into each other in astrophysical magnetic fields...

Detecting a primordial black hole (PBH) would be an outstanding discovery with strong implications on cosmology, high-energy physics, and astrophysics. I will overview recent results about: I) individual-event searches for PBHs with gravitational-wave detectors; II) quantifying the evidence for PBHs in current data and with future detectors Einstein Telescope and LISA, using population...

There are strong indications that dark matter might exhibit self-interactions. In the case of asymmetric dark matter, such interactions might lead under certain conditions to the collapse of dark matter and the formation of compact objects. These dark stars can be probed in various ways. Firstly they have a different gravitational waveform from black holes and neutron stars in merger events....

Additionally, the talk will explore future prospects and...

In the absence of a verifiable dark matter signal in traditional direct detection or collider experiments, parallel theoretical and experimental advancement has unlocked the possibility of searching for particle dark matter lighter than the proton. In the past decade, this has allowed for rapid development of charge detection in traditional materials with eV-scale band gaps. Ongoing detector...

Low mass dark matter searches and coherent neutrino-nucleus scattering experiments using low-threshold cryogenic detectors observe excess of events at low energies close to their thresholds. This background, dubbed the Low Energy Excess, limits the sensitivity of these experiments. There has been a worldwide effort to understand the origin of these events over the past years. I will report on...

I will review the motivation for pursuing the direction-sensitive detection of dark matter, e.g. for confirming the galactic origin of a signal, or for exploring into the neutrino fog. I will then review experimental methods that can perform such measurements across the dark matter model landscape, and highlight recent progress in the field.

I will review the status of indirect searches for dark matter, including those using cosmic ray antimatter, gamma rays, and photons at other wavelengths. I will also summarize several of the anomalies and excesses that have been reported in the literature, and discuss ways in which the origins of these would-be signals for dark matter could be clarified.

Antiparticles are a natural component of cosmic radiation since they are produced in the interaction between cosmic rays and interstellar matter. Cosmic-ray positrons and antiprotons were first observed in pioneering experiments in the sixties and seventies, respectively. Since their first observation, it has been apparent that cosmic-ray antimatter can shed light on the nature of dark...

The nature of dark matter (DM) has played a critical role in the formation of the first luminous objects of the universe. A distinguishing characteristic of DM models is their small-scale density fluctuations, which would have affected the abundance of minihalos and the first galaxies, and can be probed through features in the global evolution and spatial fluctuations of the 21-cm signals from...

regarding the prospects for SUSY dark matter, but this is based on old
prejudices from the 20th century. A proper calculation of electroweak
finetuning reveals the LSP should be a light higgsino state which is
thermally underproduced. But solving the strong CP problem requires
a QCD axion, and the DFSZ model which... -

DAMA/LIBRA has successfully developed ultra-high purity NaI(Tl) detectors which have been operated underground for about 20 years. A modulation signal compatible with the expected DM modulation is observed with an exposure of order 3 ton x yr. Any hint of a possible observation of a DM signal deserves deep examination. Therefore, testing the DAMA/LIBRA finding is of crucial interest and in...
