The PAU Survey: Uncovering the connection between intrinsic and observed galaxy properties using symbolic regression
Adarsh Kumar, Carlton M. Baugh, Suttikoon Koonkor +12
Estimating stellar masses for billions of galaxies in upcoming surveys requires methods that are both accurate and computationally efficient. We present a new approach using symbol…
Exploring Coupled Quintessence in light of CMB and DESI DR2 measurements
Atul Ashutosh Samanta, Abhijith Ajith, Sukanta Panda
We perform a detailed analysis of a theoretically motivated dark energy quintessence model which interacts with the dark matter sector of the universe. Utilising the current observ…
Scalar and vector modes in inflation with antisymmetric tensor field
Abhijith Ajith, Sukanta Panda
We investigate the scalar and vector modes arising from cosmological perturbations within the framework of an inflationary scenario driven by an antisymmetric tensor field, minimal…
Constraints on Bianchi-I type universe with SH0ES anchored Pantheon+ SNIa data
Anshul Verma, Sanjeet K. Patel, Pavan K. Aluri +2
We study the Bianchi-I cosmological model motivated by signals of statistical isotropy violation seen in cosmic microwave background (CMB) observations and others. To that end, we…
