Studying X-ray instruments with galaxy clusters

J. Nevalainen, S. Molendi

We applied a scientific approach to the problem of the effective area cross-calibration of the XMM-Newton EPIC instruments. Using a sample of galaxy clusters observed with the XMM-…

A search for the missing baryons with X--ray absorption lines towards the blazar 1ES 1553+113

D. Spence, M. Bonamente, J. Nevalainen +5

This paper presents an analysis of XMM X--ray spectra of the quasar 1ES 1553+113, in search for absorption lines from the intervening warm--hot intergalactic medium. A search for O…

Cosmic gas highways in C-EAGLE simulations

I. Vurm, J. Nevalainen, S. E. Hong +3

A substantial fraction of the cosmic baryons is expected to hide in the form of diffuse warm-hot intergalactic medium (WHIM), the majority of which resides in the filaments of the…

Cosmic metal invaders: Intergalactic OVII as a tracer of the warm-hot intergalactic medium within cosmic filaments in the EAGLE simulation

T. Tuominen, J. Nevalainen, P. Heinämäki +5

The current observational status of the hot (log T(K) > 5.5) warm-hot intergalactic medium (WHIM) remains incomplete. While recent observations from stacking large numbers of Cosmi…

Quasi-spherical superclusters

Pekka Heinämäki, Pekka Teerikorpi, Marian Douspis +5

Generally the dynamical state of superclusters is poorly known. We study properties of superclusters and select a sample of quasi-spherical superclusters, the dynamics of which can…

The Scaling Relation between Galaxy Luminosity and WHIM Density from EAGLE Simulations with application to SDSS data

Patrick Holt, Toni Tuominen, Jukka Nevalainen +4

This paper presents an updated scaling relation between the optical luminosity density (LD) of galaxies in the band and the density of the warm-hot intergalactic medium (WHIM)…
