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…

Sub-millimeter galaxies in hierarchical models: revisiting the need for a top-heavy stellar initial mass function with Bayesian optimisation

Edward Elliott, C. M. Baugh, Cedric Lacey

The properties of high-redshift sub-millimetre galaxies (SMGs) remain controversial within hierarchical structure formation models. We revisit whether a top-heavy stellar initial m…

The PAU Survey: The -band galaxy luminosity function from the present-day to

S. Koonkor, C. M. Baugh, G. Manzoni +13

We present a measurement of the -band galaxy luminosity function from the present-day to , using over 1.1 million galaxies from the Physics of the Accelerating Universe S…

The PAU Survey: Enhancing photometric redshift estimation using DEEPz

I. V. Daza-Perilla, M. Eriksen, D. Navarro-Gironés +20

We present photometric redshifts for 1 341 559 galaxies from the Physics of the Accelerating Universe Survey (PAUS) over 50.38 of sky to . Redshift e…

The PAU Survey: galaxy stellar population properties estimates with narrowband data

Benjamin Csizi, Luca Tortorelli, Małgorzata Siudek +17

Narrowband galaxy surveys have recently gained interest as a promising method to achieve the necessary accuracy on the photometric redshift estimate of individual galaxies for stag…
