Detection of polarized gamma-ray emission from the Crab nebula with the Hitomi Soft Gamma-ray Detector† [PDF]

open access: yesNippon Tenmon Gakkai obun kenkyu hokoku, 2018
We present the results from the Hitomi Soft Gamma-ray Detector (SGD) observation of the Crab nebula. The main part of SGD is a Compton camera, which in addition to being a spectrometer, is capable of measuring polarization of gamma-ray photons.

Revealing the velocity structure of the filamentary nebula in NGC 1275 in its entirety. [PDF]

open access: yes, 2018
We have produced for the first time a detailed velocity map of the giant filamentary nebula surrounding NGC 1275, the Perseus cluster’s brightest galaxy, and revealed a previously unknown rich velocity structure across the entire nebula.

Discovery of an X-Ray Photoionized Optical Nebula and a Radio Nebula Associated with the ULX NGC 4861 X-1

open access: yesThe Astrophysical Journal, 2023
We have conducted long-slit spectroscopic observations and analyzed archival radio data for the ultraluminous X-ray source (ULX) NGC 4861 X-1. Our spectral line analysis unveils NGC 4861 X-1 as the fourth ULX situated within an X-ray photoionized nebula,

M 1–92 Revisited: New Findings and Open Questions: New NOEMA Observations of Minkowski’s Footprint

open access: yesGalaxies, 2022
PN M 1–92, also known as Minkowski’s Footprint, is a textbook example of a massive pre-planetary nebula. It presents all the characteristics of this type of source: non-spherical symmetry (bipolar cylindrical symmetry in this case), high-velocity gas ...
