Predicting spectral features in galaxy spectra from broad-band photometry
F. B. Abdalla, A. Mateus, W. A. Santos +3
We explore the prospects of predicting emission line features present in galaxy spectra given broad-band photometry alone. There is a general consent that colours, and spectral fea…
Searching for Star Formation Outside Galaxies: Multiwavelength Analysis of the Intragroup Medium of HCG100
Duilia F. de Mello, Sergio Torres-Flores, Claudia L. Mendes de Oliveira
We used multiwavelength data (HI, FUV, NUV, R) to search for evidence of star formation in the intragroup medium of the Hickson Compact Group 100. We find that young star-forming r…
The compact group--fossil group connection: observations of a massive compact group at z=0.22
Claudia L. Mendes de Oliveira, Eleazar R. Carrasco
It has been suggested that fossil groups could be the cannibalized remains of compact groups, that lost energy through tidal friction. However, in the nearby universe, compact grou…
The Solar Radius in the EUV during the Cycle XXIII
C. G. Giménez de Castro, A. C. V. Saraiva, J. E. R. Costa +1
Aims. To determine the solar transition region and coronal radius at EUV wavelengths and its time evolution during Solar Cycle XXIII. Methods. We use daily 30.4 and 17.1 nm images…
Witnessing the formation of a galaxy cluster at z=0.485: optical and X-ray properties of RX J1117.4+0743 ([VMF 98] 097)
E. R. Carrasco, E. S. Cypriano, G. B. Lima Neto +4
We present a multiwavelength study of the poor cluster RX J1117.4+0743 ([VMF 98] 097) at z=0.485, based on GMOS/Gemini South g', r' photometry and spectroscopy, and XMM-Newton obse…
Exploring the connection between the stellar wind and the non-thermal emission in LS 5039
V. Bosch-Ramon, C. Motch, M. Ribo +5
LS 5039 has been observed with several X-ray instruments so far. The source presents X-ray variability at orbital timescales in flux and photon index. The system harbors an O-type…
