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...
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...
This talk will review the experimental landscape of axion and axion-like particle searches and introduce the various types of setups employed to look for the elusive particle initially proposed to solve the strong CP problem.
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...
I review the status of dark matter theory, and present a series of challenges for the discovery road ahead.
This talk will present an overview of the experimental efforts to detect WIMP dark matter and other particle candidates with masses above 1 GeV, along with the prospects for finally identifying the nature and origin of dark matter.
This talk will focus on recent advancements in dark matter searches at the GeV scale. I will present the latest results from major experiments, such as those conducted at underground laboratories and physics facilities, emphasising the detection mechanisms and the methods used to identify potential dark matter signals over backgrounds. 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...
I will present recent advancements in the search for dark matter (DM) which span a wide energy spectrum from MeV to PeV.
For MeV DM, the INTEGRAL satellite has provided stringent constraints through gamma-ray observations, while X-ray data from the XMM-Newton observatory has offered critical insights into sub-GeV DM, further narrowing the parameter space.
At higher energies, the Fermi Large...
I will discuss recent advancements in N-body simulations of self-interacting dark matter and their implications for the latest astrophysical observations of diverse galactic systems, including spiral galaxies, ultra-diffuse galaxies, and satellite galaxies of the Milky Way. I will highlight the novel signatures of gravothermal collapse in dark matter halos and explore their detection...
There is rampant pessimism in the collder and dark matter communities
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...
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...
