PSR B0656+14: the unified outlook from the infrared to X-rays

Understand

We report detection of PSR B0656$+$14 with the Gran Telescopio Canarias in narrow optical $F657$, $F754$, $F802$, and $F902$ and near-infrared $JHK_s$ bands.

• The pulsar detection in the $K_s$ band extends its spectrum to 2.2 $\mu$m and confirms its flux increase towards the infrared.
• We also present a thorough analysis of the optical spectrum obtained by us with the VLT.
• For a consistency check, we revised the pulsar near-infrared and narrow-band photometry obtained with the \textit{HST}.
