Protostellar Jets in Star Cluster Formation and Evolution. I. Implementation and Initial Results
The Astronomical JournalStars form in clusters from the gravitational collapse of giant molecular clouds, which is opposed by a variety of physical processes, including stellar feedback. The interplay between these processes determines the star formation rate of the clouds.

Associations of Sleep and Shift Work With Osteoarthritis Risk
Arthritis Care &Research, EarlyView.Objective Daily rhythms may be critical for maintaining homeostasis of joint tissues. We aimed to investigate the relationships among circadian clock disruption, sleep, and osteoarthritis (OA) risk in humans. Methods In the UK Biobank, a prospective 500,000–person cohort, we evaluated associations among sleep duration, sleeplessness/insomnia, and shift

Stellar-wind-blown Bubbles as Environments for Late-time Rebrightening of Gamma-ray Burst Afterglows
The Astrophysical Journal LettersWe present multiwavelength afterglow fitting results for three events that exhibit late afterglow rebrightening behavior: EP240414a ( z = 0.401), GRB 240529A ( z = 2.695), and GRB 240218A ( z = 6.782), which span a broad range of redshifts, from the ...

The Astrophysical JournalWhile stellar jets and outflows are fueled by accretion from disks, their direct influence on disks remain unexplored. Here, we revisit Atacama Large Millimeter/submillimeter Array observations of ^12 CO ( J = 2–1) line emission for the young stellar ...

, 2008 With a goal of understanding the conditions under which jets might be produced in novae and related objects, I consider the conditions under which jets are produced from other classes of accreting compact objects. I give an overview of accretion disk spectral states, including a discussion of in which states these jets are seen.

Shooting for the Stars: Jet-mode Feedback and AGN Jet Deceleration from Stellar Mass Loading
The Astrophysical JournalActive Galactic Nucleus (AGN) jets are thought to be vital ingredients in galaxy evolution through the action of kinetic feedback; however, how narrow, relativistic outflows couple to galaxies remains an open question.

A Novel Method of Modeling Extended Emission of Compact Jets: Application to Swift J1727.8−1613
The Astrophysical Journal LettersFlat radio spectra of compact jets launched by both supermassive and stellar-mass black holes (BHs) are explained by an interplay of self-absorbed synchrotron emission up to some distance along the jet and optically thin synchrotron at larger distances ...
