Detection of an Explosive Outflow in G34.26+0.15
This paper reports on the detection of a likely explosive outflow in the high-mass star-forming complex G34.26+0.15, adding to the small number (six) of explosive outflows detected so far. ALMA CO(2–1) and SiO(5–4) archival observations…

Revisiting Open Clusters within 200 pc in the Solar Neighborhood with Gaia DR3
In this study, we develop a membership identification method and apply it for 30 open clusters (OCs) within 200 pc of the Sun using astrometric data of Gaia DR3. By accounting for projection effects that distort apparent stellar motions, our…

Open-source High-resolution Exoplanet Atmosphere Retrievals with POSEIDON
High-resolution spectroscopy (R > 25,000) has opened new opportunities to characterize exoplanet atmospheres from the ground. By resolving individual lines in planetary emission and transmission spectra, one can sensitively probe the chemical…

Auto-BUQ: Uncertainty Quantification for the Boundaries of Segmented Events
We present a new method to estimate the boundary of extended sources in high-energy photon lists and to quantify the uncertainty in the boundary. This method extends the graphed seeded region growing method developed by M. Fan et al. Here, we…

Deep Synoptic Array Science: A 50 Mpc Fast Radio Burst Constrains the Mass of the Milky Way Circumgalactic Medium
We present the Deep Synoptic Array (DSA-110) discovery and interferometric localization of the so far nonrepeating FRB 20220319D. The FRB originates in a young, rapidly star-forming barred spiral galaxy, IRAS 02044+7048, at just 50 Mpc. Although…

Investigating Embedded Structures and Gas Kinematics in the Infrared-dark Cloud Hosting Bubble N59-North
We present a multiwavelength study of an extended area hosting the bubble N59-North to explore the physical processes driving massive star formation (MSF). The Spitzer 8 μm image reveals an elongated/filamentary infrared-dark cloud (length ∼28…
