KIC 10975348: A double-mode or triple-mode high-amplitude Scuti star?
Tao-Zhi Yang, Xiao-Ya Sun, Zhao-Yu Zuo +1
In this paper, we analyze the light variations of KIC 10975348 using photometric data delivered from mission. This star is exceptionally faint ( = 18.6 mag), compar…
Running Hubble Tension and a H0 Diagnostic
Chethan Krishnan, Eoin Ó Colgáin, M. M. Sheikh-Jabbari +1
Hubble tension is routinely presented as a mismatch between the Hubble constant determined locally and a value inferred from the flat CDM cosmology. In essence, the tensio…
Model-Independent Perspectives on Coupled Dark Energy and the Swampland
Tao Yang
We present a general model-independent approach to study the coupled dark energy and the string Swampland criteria. We show how the dark sector interaction is degenerated with the…
Hubble Sinks In The Low-Redshift Swampland
Aritra Banerjee, Haiying Cai, Lavinia Heisenberg +3
Local determinations of the Hubble constant favour a higher value than Planck based on CMB and CDM. Through a model-independent expansion, we show that low redshift ($z \l…
The first simultaneous measurement of Hubble constant and post-Newtonian parameter from Time-Delay Strong Lensing
Tao Yang, Simon Birrer, Bin Hu
Strong gravitational lensing has been a powerful probe of cosmological models and gravity. To date, constraints in either domain have been obtained separately. We propose a new met…
Is there an early Universe solution to Hubble tension?
Chethan Krishnan, Eoin Ó Colgáin, Ruchika +3
We consider a low redshift cosmological dataset comprising megamasers, cosmic chronometers, type Ia SNe and BAO, which we bin according to their redshift. For each bin, w…
