Optical Spectroscopy and Photoionization Model of Planetary Nebula NGC 6572

Journal of Mathematical and Fundamental Sciences
We investigated NGC 6572 through optical spectroscopy to determine its kinematical and chemical properties. Two intermediate dispersion spectra (R~5000) centered around Hα and Hβ were used to derive the nebular expansion velocity from emission lines ...

Modeling Ionized Gas in the Small Magellanic Cloud: The Wolf–Rayet Nebula N76

The Astrophysical Journal
We present Cloudy modeling of infrared emission lines in the Wolf–Rayet (WR) nebula N76 caused by one of the most luminous and hottest WR stars in the low metallicity Small Magellanic Cloud.

Likely Detection of GeV γ-Ray Emission from Pulsar Wind Nebula G32.64+0.53 with Fermi-LAT

The Astrophysical Journal
In this study, we report the likely GeV γ -ray emissions originating from the pulsar PSR J1849-0001's pulsar wind nebula (PWN) G32.64+0.53. Our analysis covers approximately 14.7 yr of data from the Fermi Large Area Telescope Pass 8.
