On the nature of the X-ray absorption in the Seyfert 2 galaxy NGC 4507 [PDF]
, 1997 We present results of the ASCA observation of the Seyfert 2 galaxy NGC 4507. The 0.5-10 keV spectrum is rather complex and consists of several components: (1) a hard X-ray power law heavily absorbed by a column density of about 3 10^23 cm^-2, (2) a ...
