Intracluster Light as a Probe for Dark Matter: Exploring Self-interacting Dark Matter and Cold Dark Matter with C-EAGLE Sims
Jaewon Yoo, Ellen L. Sirks, Cristiano G. Sabiu +5
We assess whether intracluster light (ICL) can serve as an observational discriminator of dark matter physics. The self-interacting dark matter (SIDM) model has gained increasing a…
Minkowski Functionals of the 21 cm Signal as a Probe of Primordial Features
Kanan Virkar, Suvedha Suresh Naik, Pravabati Chingangbam
The redshifted 21 cm signal from the cosmic dawn and Epoch of Reionization (EoR) encodes important information about both astrophysical processes and primordial physics, such as in…
Lyα Intensity Mapping in HETDEX: Galaxy-Lyα Intensity Cross-Power Spectrum
Maja Lujan Niemeyer, Eiichiro Komatsu, José Luis Bernal +18
We present a measurement of the Lyman- (Ly) intensity mapping power spectrum from the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX). We measure the cross-power spect…
Alleviating Cosmological Tensions with the Hadrosymmetric Twin Higgs
Mohammad Soroori Sotudeh, Zahra Davari, Sara Khatibi +1
The Hadrosymmetric Twin Higgs (HTH) model provides a natural solution to the little hierarchy problem by incorporating all three generations of quarks in a twin sector. Unlike othe…
On the shape of pancakes: catastrophe theory and Gaussian statistics in 2D
Abineet Parichha, Stephane Colombi, Shohei Saga +1
Cold dark matter (CDM) can be thought of as a 2D (or 3D) sheet of particles in 4D (or 6D) phase-space due to its negligible velocity dispersion. The large-scale structure, also cal…
Post-collapse Lagrangian perturbation theory in three dimensions
Shohei Saga, Stéphane Colombi, Atsushi Taruya +2
The gravitational collapse of collisionless matter leads to shell-crossing singularities that challenge the applicability of standard perturbation theory. Here, we present the firs…
