No need to know: astrophysics-free gravitational-wave cosmology

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Amanda M. Farah, Thomas A. Callister, Jose María Ezquiaga, Michael Zevin, Daniel E. Holz | Summary: Gravitational waves from merging compact objects encode direct information about the luminosity distance to the binary. When paired with a redshift measurement, this enables standard-siren cosmology: a Hubble diagram can […]

Resolving the nature and putative nebular emission of GS9422: an obscured AGN without exotic stars

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Sandro Tacchella, William McClymont, Jan Scholtz, Roberto Maiolino, Xihan Ji | Summary: Understanding the sources that power nebular emission in high-redshift galaxies is fundamentally important not only for shedding light onto the drivers of reionisation, but to constrain stellar populations and the growth of black holes. Here […]

Mass calibration of DES Year-3 clusters via SPT-3G CMB cluster lensing

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: B. Ansarinejad, S. Raghunathan, T. M. C. Abbott, P. A. R. Ade, M. Aguena | Summary: We measure the stacked lensing signal in the direction of galaxy clusters in the Dark Energy Survey Year 3 (DES Y3) redMaPPer sample, using cosmic microwave background (CMB) temperature data from […]

Universal Bound on Effective Central Charge and Its Saturation

Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Andreas Karch, Yuya Kusuki, Hirosi Ooguri, Hao-Yu Sun, Mianqi Wang | Summary: The effective central charge (denoted by $c_{text{eff}}$) is a measure of entanglement through a conformal interface, while the transmission coefficient (encoded in the coefficient $c_{LR}$ of the two-point function of the energy-momentum tensor across the […]

Constraints on Dark Matter from Dynamical Heating of Stars in Ultrafaint Dwarfs. Part 2: Substructure and the Primordial Power Spectrum

Kavli Affiliate: Peter W. Graham | First 5 Authors: Peter W. Graham, Harikrishnan Ramani, , , | Summary: There is a large and growing interest in observations of small-scale structure in dark matter. We propose a new way to probe dark matter structures in the $sim 10 – 10^8 , M_odot$ range. This allows us […]

Repeating Nuclear Transients as Candidate Electromagnetic Counterparts of LISA Extreme Mass Ratio Inspirals

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Shubham Kejriwal, Vojtech Witzany, Michal Zajacek, Dheeraj R. Pasham, Alvin J. K. Chua | Summary: Extreme-mass-ratio inspirals (EMRIs) are one of the primary targets for the recently adopted millihertz gravitational-wave (GW) observatory LISA. Some previous studies have argued that a fraction of all EMRIs form in […]
