Very-high-energy $\\gamma$-ray emission provides constraints on the morphology and the physics mechanisms involved in the evolution of pulsar wind nebulae (PWNe). In the Galactic plane, around $312 ^{\\circ}$ of Galactic longitude, a promising region two-degree wide containing five powerful pulsars may offer a new insight on the transition between TeV-emitting PWNe and pulsar halos.

PSR B0540−69 (hereafter B0540) is a P = 50 ms pulsar discovered in X-rays by the Einstein Observatory (Seward, Harnden & Helfand 1984) and then in radio from Parkes (Manchester et al. 1993). It is located in the large magellanic cloud (LMC) rendering it the first extragalactic pulsar discovered. ... and found A γ = 16.88 kyr and γ = 0.86.Abstract. Context. The characteristic age of PSR J1734-3333 estimated from its current spin down rate implies that it is a young pulsar (τc = 8.1 kyr).

In general, the rotation would exhibit irregularities for adolescence pulsars, which have characteristic ages less than ∼ 100 kyr. PSR J0940–5428 has a relatively lower characteristic age τ c ∼ 42.2 kyr and a similar period as Vela Pulsar, and, importantly, PSR J0940–5428 is a source of radio, X-ray and γ-ray radiations.

The timing solution, reported by Levin et al. , implies a very high surface magnetic field of B≈ 2.8 × 10 14 G and a characteristic age of τ c ≈ 4 kyr. PSR J1622-4950 has a flat radio spectrum and a highly variable flux density and pulse profile [8 - 10, 16, 89], which is similar to other radio magnetars.The exception is the 11 kyr old Vela pulsar, where frequent large glitches prevent a phase-coherent measurement of the braking index, but measuring in the aftermath of glitches has allowed a measurement of n = 1.4 ± 0.2 over ∼25 years of data (Lyne et al. 1996). The initial goal of timing PSR J0205+6449 was to measure its braking index.
