Kinematic Lensing Ratio: Reviving Weak Lensing Cosmography as a Geometric Dark Energy Probe
Qinxun Li
We introduce the kinematic lensing ratio (KiLeR), a geometric dark-energy probe from weak lensing. Combining shear ratios with intrinsic galaxy shapes inferred from kinematics, KiL…
Constraining primordial non-Gaussianity from DESI DR1 quasars and Planck PR4 CMB Lensing
Sofia Chiarenza, Alex Krolewski, Marco Bonici +54
We present the first measurement of local-type primordial non-Gaussianity from the cross-correlation between million spectroscopically confirmed quasars from the first data r…
XRISM constraints on the velocity power spectrum in the Coma cluster
D. Eckert, M. Markevitch, J. A. ZuHone +6
The velocity field of intracluster gas in galaxy clusters contains key information on the virialization of infalling material, the dissipation of AGN energy into the surrounding me…
Clustering analysis of medium-band selected high-redshift galaxies
H. Ebina, M. White, A. Raichoor +57
Next-generation large-scale structure spectroscopic surveys will probe cosmology at high redshifts , relying on abundant galaxy tracers such as Ly emitters (LAE…
The structure of the giant radio fossil in the Ophiuchus galaxy cluster
Simona Giacintucci, Maxim Markevitch, Tracy Clarke +1
We present high-sensitivity follow-up observations of the giant fossil radio lobe in the Ophiuchus galaxy cluster with the upgraded Giant Metrewave Radio Telescope (uGMRT) in the 1…
Combined tracer analysis for DESI 2024 BAO
D. Valcin, M. Rashkovetskyi, H. Seo +64
This paper demonstrates how the Dark Energy Spectroscopic Instrument (DESI) Data Release 1 (DR1) and future baryon acoustic oscillations (BAO) analyses can optimally combine overla…
