Abstract: The discovery of quasar J1342+0928 (z=7.54) reinforces the time compression problem associated with the premature formation of structure in LCDM. Adopting the Planck parameters, we see this quasar barely 690 Myr after the big bang,… read more here.

DOI: 10.1103/physrevd.107.103012
Abstract: We study the detectability of gravitational-wave signals from sub-solar mass binary neutron star systems by the current generation of ground-based gravitational-wave detectors. We find that finite size effects from large tidal deformabilities of the neutron… read more here.

DOI: 10.1103/physrevd.98.103024
Abstract: We describe detection methods for extensions of gravitational wave searches to sub-solar mass compact binaries. Sub-solar mass searches were previously carried out using Initial LIGO, and Advanced LIGO boasts a detection volume approximately 1000 times… read more here.

DOI: 10.1103/physrevlett.126.071101
Abstract: Solar-mass black holes with masses in the range of ∼1-2.5 M_{⊙} are not expected from conventional stellar evolution, but can be produced naturally via neutron star (NS) implosions induced by capture of small primordial black holes… read more here.
