TL;DR: In this paper, the optical and radio data on the BL Lacertae object AO 0235+16 have been collected in the last four years by a wide international collaboration, which confirm the intense activity of this source.
Long-term optical monitoring of TeV emitting blazars
Kari Nilsson,Elina Lindfors,L. O. Takalo,R. Reinthal,Andrei Berdyugin,A. Sillanpää,S. Ciprini,A. Halkola,Pekka Heinämäki,Talvikki Hovatta,V. Kadenius,P. Nurmi,L. Ostorero,M. Pasanen,R. Rekola,Jari Saarinen,J. Sainio,T. Tuominen,Carolin Villforth,T. Vornanen,B. Zaprudin +20 more
TL;DR: In this paper, the authors present 10 years of R-band monitoring data of 31 northern blazars which were either detected at very high energy (VHE) gamma rays or listed as potential VHE gamma-ray emitters.
The richest superclusters. I. Morphology
Maret Einasto,Enn Saar,L. J. Liivam"agi,Jaan Einasto,Erik Tago,Vicent J. Martínez,Jean-Luc Starck,V. M"uller,P. Hein"am"aki,P. Nurmi,M. Gramann,G. H"utsi +11 more
TL;DR: In this paper, the morphology of the richest superclusters from the catalogues of super-clusters of galaxies in the 2dF Galaxy Redshift Survey was studied and compared with model supercluster in the Millennium Simulation.

TL;DR: In this article, a morphological study of the two richest superclusters from the 2dF Galaxy Redshift Survey (SCL126, the Sloan Great Wall, and SCL9, the Sculptor supercluster) is presented.

Missing baryons traced by the galaxy luminosity density in the large-scale WHIM filaments
Jukka Nevalainen,Elmo Tempel,L. J. Liivamägi,E. Branchini,Mauro Roncarelli,Carlo Giocoli,Pekka Heinämäki,Enn Saar,Antti Tamm,A. Finoguenov,P. Nurmi,M. Bonamente +11 more
TL;DR: In this article, the authors proposed a new approach to the missing baryons problem based on the common assumption that the missing bits are in the form of the Warm Hot Intergalactic Medium (WHIM), and they further assumed that the galaxy luminosity density can be used as a tracer of the WHIM.
