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…
