WebApr 9, 2024 · NGC 4151, a nearby Seyfert galaxy, has recently been reported to emit gamma rays in the GeV range, posing an intriguing astrophysical mystery. The star formation rate of NGC 4151 is too low to explain the observed GeV flux, but the galaxy is known for its coronal activity in X-ray and jet activity in radio. We propose that either the … WebOct 8, 2024 · 1 Answer. Sorted by: 1. I'll assume the region of integration is [ 0, ∞). The previous form you had for the integral was actually better since we can identify it as. 1 Γ ( s) ∫ 0 ∞ x s − 1 e − x ln Γ ( x) d x = 1 Γ ( s) M { e − x ln Γ ( x) } ( s) However this is unfortunately still quite bothersome. So perhaps we can use the ...
