In this work, we study theoretical and observational issues about pulsars (PSRs), pulsar
wind nebulae (PWNe) and supernova remnants (SNRs). In particular, the spectral modeling
of young PWNe and the X-ray analysis of SNRs with magnetars comparing their characteristics
with those remnants surrounding canonical pulsars.
The spectra of PWNe range from radio to γ-rays. They are the largest class of identified
Galactic in γ-rays increasing the number from 1 to ∼30 during the last years. We have developed
a detailed spectral code which reproduces the electromagnetic spectrum of PWNe in
free expansion (tage .10 kyr). We shed light and try to understand issues on time evolution
of the spectra, the synchrotron self-Compton dominance in the Crab Nebula, the particle
dominance in PWNe detected at TeV energies and how physical parameters constrain the
detectability of PWNe at TeV. We make a systematic study of all Galactic, TeV-detected,
young PWNe which allows to find correlations and trends between parameters. We also
discuss about the spectrum of those PWNe not detected at TeV and if models with low magnetized
nebulae can explain the lack of detection or, on the contrary, high-magnetization
models are more favorable.
Regarding the X-ray analysis of SNRs, we use X-ray spectroscopy in SNRs with magnetars
to discuss about the formation mechanism of such extremely magnetized PSRs. The
alpha-dynamo mechanism proposed in the 1990’s produces an energy release that should
have influence in the energy of the SN explosion. We extend the work done previously done
by Vink & Kuiper (2006) about the energetics of the SN explosion looking for this energy
release and we look for the element ionization and the X-ray luminosity and we compare
our results with other SNRs with an associated central source.
