Detecting microvariability in type 2 quasars using enhanced F-test
J. Polednikova, A. Ederoclite, J. A. de Diego +9
Microvariability (intra-night variability) is a low amplitude flux change at short time scales (i.e. hours). It has been detected in unobscured type 1 AGNs and blazars. However in…
Multi-wavelength landscape of the young galaxy cluster RXJ1257.2+4738 at z=0.866. II. Morphological properties
I. Pintos-Castro, M. Povic, M. Sánchez-Portal +11
The study of the evolution of the morphological distribution of galaxies in different environments can provide important information about the effects of the environment and the ph…
Testing microvariability in quasar differential light curves using several field stars
J. A. de Diego, J. Polednikova, A. Bongiovanni +4
Microvariability consists in small time scale variations of low amplitude in the photometric light curves of quasars, and represents an important tool to investigate their inner co…
San Pedro Martir observations of microvariability in obscured quasars
Jana Polednikova, Alessandro Ederoclite, Jordi Cepa +9
Fast brightness variations are a unique tool to probe the innermost regions of active galactic nuclei (AGN). These variations are called microvariability or intra-night variability…
GLACE survey: OSIRIS/GTC Tuneable Filter H imaging of the rich galaxy cluster ZwCl 0024.0+1652 at z = 0.395. Part I -- Survey presentation, TF data reduction techniques and catalogue
Miguel Sánchez-Portal, Irene Pintos-Castro, Ricardo Pérez-Martínez +35
The cores of clusters at 0 z 1 are dominated by quiescent early-type galaxies, whereas the field is dominated by star-forming late-type ones. Galaxy propertie…
Multi-wavelength landscape of the young galaxy cluster RXJ1257.2+4738 at z=0.866: I. The infrared view
I. Pintos-Castro, M. Sánchez-Portal, J. Cepa +16
We performed a thorough analysis of the star formation activity in the young massive galaxy cluster RXJ1257+4738 at z=0.866, with emphasis on the relationship between the local env…
Lyman break and UV-selected galaxies at z ~ 1: II. PACS-100um/160um FIR detections
I. Oteo, G. Magdis, Á. Bongiovanni +53
We report the PACS-100um/160um detections of a sample of 42 GALEX-selected and FIR-detected Lyman break galaxies (LBGs) at z ~ 1 located in the COSMOS field and analyze their ultra…
Lyman break and UV-selected galaxies at I. Stellar populations from ALHAMBRA survey
I. Oteo, Á. Bongiovanni, J. Cepa +29
We take advantage of the exceptional photometric coverage provided by the combination of GALEX data in the UV and the ALHAMBRA survey in the optical and near-IR to analyze the phys…
Testing black hole no-hair theorem with OJ287
M. J. Valtonen, S. Mikkola, H. J. Lehto +3
We examine the ability to test the black hole no-hair theorem at the 10% level in this decade using the binary black hole in OJ287. In the test we constrain the value of the dimens…
