Decomposing the Spectrum of Ultra-Luminous X-ray Pulsar NGC 300 ULX-1
A phase-resolved analysis on the X-ray spectrum of Ultra-Luminous X-ray
Pulsar (ULXP) NGC 300 ULX-1 is performed with data taken with XMM-Newton and
NuSTAR on 2016 December 16th. In addition to the classical phase-restricting
analysis, a method developed in active galactic nuclei studies is newly
employed for ULXP. It has revealed that the pulsation cycle of the source can
be divided into two intervals in terms of X-ray variability. This suggests the
rotating flow consists of at least two representative emission regions.
Furthermore, the new method successfully decomposed the spectrum into an
independent pair in each interval. One is an unchanging-component spectrum that
can be reproduced by a standard disk model with a km inner
radius and a keV peak temperature. The other is the spectrum of
the component that coincides with the pulsation. This was explained with a
Comptonization of a keV blackbody and exhibited a harder
photon index in the brighter phase interval of two. The results are consistent
with a picture that the pulsating emission originates from a funnel-like flow
formed within the magnetosphere, and the inner flow exhibiting a harder
continuum is observed exclusively when the opening cone points to the observer.Comment: 27 pages, 15 figures, accepted for publication in Ap
New herpetofaunal records from Gunung Mulu National Park and its surrounding areas in Borneo
Gunung Mulu National Park (GMNP) in northwestern Borneo is marked by high species diversity and diverse environments. We present one new amphibian and ten new reptile records from GMNP and its surrounding area. In the records, Asthenodipsas jamilinaisi and Garthius chaseni were newly recorded in the Sarawak State. We also present the first record of Cyrtodactylus muluensis from outside of GMNP and the second record of Opisthotropis typica from the park. Combined with previous information, a total of 108 amphibians and 104 reptiles are known from GMNP, and their preferred habitat types are diverse. Furthermore, observed male-male combat of Dopasia buettikoferi is the first detailed description of the genus. Two color morphs of D. buettikoferi had an identical ND2 haplotype and appeared to be the same species. The present study provides new information about Bornean amphibians and reptiles, and also emphasizes the importance of continuous monitoring
