Alleviating the need for exponential evolution of JWST galaxies in 10 haloes at by a modified CDM power spectrum
Hamsa Padmanabhan, Abraham Loeb
We infer the evolution of the UV luminosities of galaxies in haloes of masses in the redshift range of from the recent JWST data. Within…
A new approach to constrain the Hubble expansion rate at high redshifts by gravitational waves
Mohammadtaher Safarzadeh, Karan Jani, Nianyi Chen +2
Detection of massive binary black hole (BBH) mergers at high redshifts is a target for LISA space mission. While the individual masses of a BBH merger are redshifted, the mass rati…
Life on Titan May Signal Early Life in the Universe
Abraham Loeb
The temperature of the cosmic microwave background (CMB) was equal to the surface temperature of Saturn's moon Titan, 94K, at a redshift z=33.5, after the first galaxies formed. Ti…
Quantum Tunneling of Ultralight Dark Matter Out of Satellite Galaxies
Mark P. Hertzberg, Abraham Loeb
The idea of ultralight scalar (axion) dark matter is theoretically appealing and may resolve some small-scale problems of cold dark matter; so it deserves careful attention. In thi…
Ultra Long-Term Cosmology and Astrophysics
Robert J. Scherrer, Abraham Loeb
We examine astronomical observations that would be achievable over a future timeline corresponding to the documented history of human civilization so far, years. We exa…
The challenge of ruling out inflation via the primordial graviton background
Sunny Vagnozzi, Abraham Loeb
Recent debates around the testability of the inflationary paradigm raise the question of how to model-independently discriminate it from competing scenarios. We argue that a detect…
