Can We Constrain Warm Dark Matter Masses with Individual Galaxies?

The Astrophysical Journal
We study the impact of warm dark matter (WDM) mass on the internal properties of individual galaxies using a large suite of 1024 state-of-the-art cosmological hydrodynamic simulations from the DREAMS project.

Small-Scale Cosmology “Crisis” and Self-Interacting Right-Handed Neutrino Warm Dark Matter

EPJ Web of Conferences, 2018
In the lecture, I first review the basic problems of the ΔCDM model at small (galactic) scales, also known as “small-scale Cosmology crisis”, namely discrepancies between theoretical simulations and observations.

Real scalar dark matter: relativistic treatment

Journal of High Energy Physics, 2019
A stable real scalar provides one of the simplest possibilities to account for dark matter. We consider the regime where its coupling to the Standard Model fields is negligibly small.

Rapid Deep Vat Printing Using Photoclickable Collagen‐Based Bioresins

Advanced Healthcare Materials, EarlyView.
Collagen‐based resin formulations based on thiol‐ene photoclick chemistry are demonstrated. These resins enable easy handleability under neutral conditions and further allow facile fabrication of multicellular tissue constructs via tomographic or FLight printing.

Saxion cosmology for thermalized gravitino dark matter

Journal of High Energy Physics, 2017
In all supersymmetric theories, gravitinos, with mass suppressed by the Planck scale, are an obvious candidate for dark matter; but if gravitinos ever reached thermal equilibrium, such dark matter is apparently either too abundant or too hot, and is ...

Feebly interacting U(1)B−L gauge boson warm dark matter and XENON1T anomaly

Physics Letters B, 2020
The recent observation of an excess in the electronic recoil data by the XENON1T detector has drawn many attentions as a potential hint for an extension of the Standard Model (SM).

Combination of Polydopamine and Plasma Oxidation to Increase Tissue Integration of Polyurethane‐Silicone Copolymers for Cardiovascular Implants

Advanced Healthcare Materials, EarlyView.
Plasma oxidation following polydopamine deposition can significantly reduce the surface hydrophobicity of polyurethane‐siloxanes without impacting surface roughness, thereby increasing fibroblast viability, adhesion, and extracellular matrix production and secretion.

Quantum Statistical Effects on Warm Dark Matter and the Mass Constraint from the Cosmic Structure at Small Scales

The Astrophysical Journal Letters
The suppression of the small-scale matter power spectrum is a distinct feature of warm dark matter (WDM), which permits a constraint on the WDM mass from galaxy surveys. In the thermal relic WDM scenario, quantum statistical effects are not manifest.

Captures of Hot and Warm Sterile Antineutrino Dark Matter on EC-decaying Ho-163 Nuclei

, 2011
Capturing low-energy electron antineutrinos on radioactive Ho-163 nuclei, which decay into Dy-163 via electron capture (EC), is a noteworthy opportunity to detect relic sterile antineutrinos.
