The Hydrostatic Mass Bias and the Tension: A Multi-Probe Forecast for Stage-IV/V Surveys
Ayodeji Ibitoye, Prabhakar Tiwari, Qi Xiong +1
The hydrostatic mass bias () is a leading systematic uncertainty in cluster cosmology and a principal source of degeneracy with and . We investigate…
Constraining Quintessence Models with ISW-tSZ Cross-Correlations: A Comparative Analysis of Thawing, Tracker, and Scaling-Freezing Dynamics
Ayodeji Ibitoye, Shiriny Akthar, Md. Wali Hossain +5
We present constraints on quintessence dark energy models using the observational detection of the Integrated Sachs-Wolfe (ISW)--thermal Sunyaev-Zeldovich (tSZ) cross-correlation d…
Overdispersed radio source counts and excess radio dipole detection
Lukas Böhme, Dominik J. Schwarz, Prabhakar Tiwari +6
The source count dipole from wide-area radio continuum surveys allows us to test the cosmological standard model. Many radio sources have multiple components, which can cause an ov…
Cosmology from LOFAR Two-metre Sky Survey Data Release 2: Counts-in-Cells Statistics
Morteza Pashapour-Ahmadabadi, Lukas Böhme, Thilo M. Siewert +5
We investigate the statistical distribution of source counts-in-cells in the second data release of the LOFAR Two-Metre Sky Survey (LoTSS-DR2) and we test a computationally cheap m…
Cosmology from LOFAR Two-metre Sky Survey Data Release 2: Cross-correlations with luminous red galaxies from eBOSS
Jinglan Zheng, Prabhakar Tiwari, Gong-Bo Zhao +7
We cross-correlated galaxies from the LOw-Frequency ARray (LOFAR) Two-metre Sky Survey (LoTSS) second data release (DR2) radio source with the extended Baryon Oscillation Spectrosc…
