27. Status and prospects for indirect Dark Matter searches

Pedro De la Torre Luque (Institute of theoretical physics (IFT-UAM))

6/4/25, 10:00 AM

DM Indirect Detection and Astrophysics

Invited Talk

More than 80% of the matter in the Universe is made up of a substance whose nature remains one of the greatest mysteries in physics: dark matter. Although there is clear evidence of its existence and gravitational effects, no evidence has been found of dark matter interacting with Standard Model matter beyond gravity.
Astrophysical and cosmological observations serve as powerful tools to...

48. Unveiling low mass WIMP Dark Matter in the Galactic Centre through KM3NeT

Adriana Bariego Quintana (IFIC)

6/4/25, 10:35 AM

DM Indirect Detection and Astrophysics

Contributed Talk

The method of indirect detection of Dark Matter (DM) in neutrino telescopes involves the observation of a Cherenkov light pattern left by their annihilation or decay products crossing the detector. An excess of neutrinos produced by these processes is searched in astrophysical targets such as the Galactic Centre or the Sun, where large amounts of DM are believed to accumulate. An interesting...

42. Probing dark matter annihilation through planetary airglow and internal heat flow

Marianne Moore (MIT)

6/4/25, 10:55 AM

Contributed Talk

The annihilation of accumulated dark matter within planetary bodies could lead to observable signatures in the form of anomalous UV airglow and excess internal heat flow. We use existing UV and IR spectral data obtained by spaceprobe flybys of Solar System planets to constrain such effects. By comparing the measured spectra to potential dark matter-induced emissions, we place limits on...

96. Celestial objects as Leptophilic dark matter detectors

Thong T. Q. Nguyen (OKC, Stockholm University)

DM Indirect Detection and Astrophysics

Poster + Lightning Talk

With their large exposures from the heaven, celestial objects serve as natural dark matter detectors. For leptophilic dark matter, interactions with electrons inside these objects can lead to energy loss, allowing dark matter to become gravitationally bound. Using the Sun and observations by Super-Kamiokande, we set world-leading constraints on the dark matter–electron scattering cross section...

36. Nano-Hertz gravitational waves and sub-GeV dark matter form a classically conformal phase transition

Jonas Matuszak (Karlsruher Institute of Technology)

6/4/25, 11:20 AM

Galaxies, Dynamics and Cosmology

Poster + Lightning Talk

Strong first-order phase transitions offer a compelling explanation for the stochastic gravitational wave background in the nano-Hertz range measured by pulsar timing arrays (PTA). In this talk, I will consider a classically conformal dark sector in which the symmetry breaking of a dark $U(1)$ gives rise to a gravitational wave background that can fit the PTA data and additionally sources the...
