BeppoSAX Observations of 1-Jy BL Lacertae Objects - II
P. Padovani, L. Costamante, P. Giommi +3
We present new BeppoSAX LECS and MECS observations, covering the energy range 0.1 - 10 keV (observer's frame), of four BL Lacertae objects selected from the 1 Jy sample. All source…
A brief (blazar oriented) overview on topics for multi-wavelength observations with TeV photons
L. Costamante
Multi-wavelength observations with TeV photons are an essential diagnostic tool to study the physics of TeV sources. The complex variability of blazars, however (timescales from ye…
Constraining the Cosmic Background Light with four BL Lac TeV spectra
L. Costamante, F. Aharonian, D. Horns +1
The intrinsic BL Lac spectra above few hundreds GeV can be very different from the observed ones due to the absorption effects by the diffuse Extragalactic Background Light (EBL),…
The SED of the TeV BLLac 1ES 1426+428 after correction for the TeV--IR absorption
L. Costamante, F. Aharonian, G. Ghisellini +1
The recent HEGRA detection and spectrum of 1ES 1426+428 at TeV energies, once corrected for absorption using present estimates of the diffuse extragalactic IR background, suggest t…
