Early Formation of Supermassive Black Holes via Dark Star Gravitational Instability
Katherine Freese, George M. Fuller, Sohan Ghodla +4
We show that dark stars, which are dark-matter-powered stars in the early universe, can grow by accretion to masses in the range $\mathscr{O}\left ({10}^4\right )-\mathscr{O}\left…
Neural Network identification of Dark Star Candidates. II. Spectroscopy
Adiba Amira Siddiqa, Sayed Shafaat Mahmud, Cosmin Ilie
Some of the first stars in the Universe might be powered by Dark Matter (DM) annihilations, rather than nuclear fusion. Those objects, i.e. Dark stars (DS), offer a unique window i…
Supermassive Dark Stars and their remnants as a possible solution to three recent cosmic dawn puzzles
Cosmin Ilie, Jillian Paulin, Andreea Petric +1
The James Webb Space Telescope (JWST) has begun to revolutionize our view of the Cosmos. The discovery of Blue Monsters (i.e., ultra-compact yet very bright high-z galaxies) and th…
Neural Network identification of Dark Star Candidates. I. Photometry
Sayed Shafaat Mahmud, Adiba Amira Siddiqa, Cosmin Ilie
The formation of the first stars in the universe could be significantly impacted by the effects of Dark Matter (DM). Namely, if DM is in the form of Weakly Interacting Massive Part…
Reconstructing PTA measurements via early seeding of supermassive black holes
Sohan Ghodla, Cosmin Ilie
Motivated by recent findings that PTA's nHz signal may be dominated by supermassive black hole (SMBH) binaries (), and high redshift quasar observations rev…
Spectroscopic Supermassive Dark Star candidates
Cosmin Ilie, Sayed Shafaat Mahmud, Jillian Paulin +1
Dark Stars, i.e. early stars composed almost entirely of hydrogen and helium but powered by Dark Matter, could form in zero metallicity clouds located close to the center of high r…
