Evaluating Large Language Models in Scientific Discovery
Zhangde Song, Jieyu Lu, Yuanqi Du +53
Large language models (LLMs) are increasingly applied to scientific research, yet prevailing science benchmarks probe decontextualized knowledge and overlook the iterative reasonin…
Detectability of Supermassive Dark Stars with the Roman Space Telescope
Saiyang Zhang, Cosmin Ilie, Katherine Freese
The first bright objects to form in the Universe at redshift might have been Dark Stars, made primarily of hydrogen and helium but powered by dark matter. In this st…
Effects of stellar-mass primordial black holes on first star formation
Boyuan Liu, Saiyang Zhang, Volker Bromm
We use cosmological hydrodynamic zoom-in simulations and semi-analytical models to study the effects of primordial black holes (PBHs) on first star formation. Our models self-consi…
Probing below the neutrino floor with the first generation of stars
Cosmin Ilie, Caleb Levy, Jacob Pilawa +1
We show that the mere observation of the first stars (Pop III stars) in the universe can be used to place tight constraints on the strength of the interaction between dark matter a…
Constraining Dark Matter properties with the first generation of stars
Cosmin Ilie, Caleb Levy, Jacob Pilawa +1
Dark Matter (DM) can be trapped by the gravitational field of any star, since collisions with nuclei in dense environments can slow down the DM particle below the escape velocity (…
Comment on "Multiscatter stellar capture of dark matter"
Cosmin Ilie, Jacob Pilawa, Saiyang Zhang
Bramante, Delgado, and Martin [Phys. Rev. D96, 063002(2017)., hereafter BDM17] extended the analytical formalism of dark matter (DM) capture in a very important way, which allows,…
Multiscatter capture of superheavy dark matter by Pop. III stars
Cosmin Ilie, Saiyang Zhang
If captured by the gravitational field of stars or other compact objects, dark matter can self-annihilate and produce a potentially detectable particle flux. In the case of superhe…
The June 2016 Optical and Gamma-Ray Outburst and Optical Micro-Variability of the Blazar 3C454.3
Zachary R. Weaver, Thomas J. Balonek, Svetlana G. Jorstad +17
The quasar 3C454.3 underwent a uniquely-structured multi-frequency outburst in June 2016. The blazar was observed in the optical band by several ground-based telescopes in phot…
