Precise Measurements of TeV Halos around Geminga and Monogem Pulsars with HAWC

open access: yesThe Astrophysical Journal
We present the most precise measurements to date for the spatial extension and energy spectrum of the γ -ray region between a pulsar’s wind nebula and the interstellar medium, better known as the halo, present around Geminga and PSR B0656+14 (Monogem ...

Very-high-energy γ-Ray Emission from Young Massive Star Clusters in the Large Magellanic Cloud

open access: yesThe Astrophysical Journal Letters
The Tarantula Nebula in the Large Magellanic Cloud is known for its high star formation activity. At its center lies the young massive star cluster R136, providing a significant amount of the energy that makes the nebula shine so brightly at many ...

Large-scale Wind-driven Structures in the Orion Nebula

open access: yesThe Astronomical Journal
A study of [C ii ] 158 μ m and H i 21 cm spectroscopic images plus high-velocity-resolution optical and ultraviolet spectra has shown the structure of the Orion Nebula to be different from that found from the study of those data separately.

The Morphology and Kinematics of a Giant, Symmetric Nebula around a Radio-loud Quasar 3C 57: Extended Rotating Gas or Biconical Outflows?

open access: yesThe Astrophysical Journal
Gas flows between galaxies and the circumgalactic medium play a crucial role in galaxy evolution. When ionized by a quasar, these gas flows can be directly traced as giant nebulae. We present a study of a giant nebula around a radio-loud quasar, 3C 57 at

The Molecular Exoskeleton of the Ring-like Planetary Nebula NGC 3132

open access: yesThe Astrophysical Journal
We present Submillimeter Array (SMA) mapping of ^12 CO J = 2 → 1, ^13 CO J = 2 → 1, and CN N = 2 → 1 emission from the ring-like planetary nebula NGC 3132, one of the subjects of JWST Early Release Observation near-infrared imaging.
