The eROSITA X-ray luminosity function of active galactic nuclei

W. Roster, J. Buchner, M. Salvato +23

The paper measures the soft X‑ray luminosity function of active galactic nuclei using eROSITA data across a wide luminosity and redshift range, introduces a redshift‑dependent brok…

Cosmology with Intensity Mapping via Statistics Beyond the Power Spectrum in the SKAO Era

Suman Majumdar, Debanjan Sarkar, Leon Noble +38

The cosmological distribution of neutral hydrogen (HI) during the post-reionization era is highly non-Gaussian due to the underlying non-linear structure formation, complex galaxy…

Cosmological gravity on all scales V: MCMC forecasts combining large scale structure and CMB lensing for binned phenomenological modified gravity

Sankarshana Srinivasan, Shreya Prabhu, Kai Lehman +2

As cosmology rapidly approaches the data-dominated phase of stage IV large scale structure surveys, the modelling of nonlinear scales has become a serious challenge that faces the…

The ASKAP-FLASH survey: A first look at the multiwavelength properties and redshift distribution of compact radio sources

W. Roster, E. M. Sadler, E. K. Mahony +15

We present the characterisation, including a photometric redshift (photo-) analysis, of the optical counterparts (CTPs) to over 45 000 bright ( 30 mJy) comp…

C3NN-SBI: Learning Hierarchies of -Point Statistics from Cosmological Fields with Physics-Informed Neural Networks

Kai Lehman, Zhengyangguang Gong, David Gebauer +2

Cosmological analyses are moving past the well understood 2-point statistics to extract more information from cosmological fields. A natural step in extending inference pipelines t…

Why Cosmic Voids Matter: Pristine Evolution

Nico Schuster, Nico Hamaus, Alice Pisani +2

We utilize the Magneticum suite of hydrodynamical simulations to investigate the formation and evolution of cosmic voids from to present day, using cold dark matter and…
