Molecular Jets from an Evolved Protostar: Insights from JWST-ALMA Synergy
The combination of ALMA submillimeter and JWST/MIRI mid-infrared observations offers a transformative view of protostellar jets and outflows by probing cold and warm gas components across diverse physical conditions. We present a detailed comparison of gas distribution in these regimes for the jet/outflow system associated with G205.46$-$14.56S3 (HOPS 315), focusing on the inner $\sim$800 AU along the jet. ALMA CO and SiO trace both lobes of the bipolar jet, revealing high-velocity collimated j…

The Neutrino Kaleidoscope: Searches for Non-Standard Neutrino Oscillations at Neutrino Telescopes with a TeV Muon Accelerator Source
Muon accelerators, a potential technology for enabling $\mathcal{O}$(10 TeV) parton center of mass energy collisions, would also source an intense, collimated beam of neutrinos at TeV energies. The energy and size of this beam would be excellently matched as a source for existing and planned neutrino telescopes: gigaton-sized detectors of astrophysical neutrinos at and above TeV energies. In this paper, we introduce the technical considerations and scientific reach of pairing a muon accelerator…

Collimated QED Cascades with Curved Plasma Mirror
Converting light into matter has been a longstanding goal in physics, particularly the creation of electron-positron pairs through quantum electrodynamic (QED) processes. While current approaches using multiple colliding laser pulses can achieve this conversion, they struggle to produce well-collimated particle beams - a crucial requirement for practical applications. Here we demonstrate that a single ultra-intense laser pulse, when reflected from a curved plasma mirror, can generate highly col…

Canalized hyperbolic magnetoexciton polaritons by Shubnikov-de Haas effect in van der Waals semiconductors
Polariton canalization exhibits highly collimated and diffraction-free propagation characteristics in natural hyperbolic materials, holding great promise for molding the energy flow at nanoscale. Previously, the majority of canalizations are realized in phonon polaritons. Herein, we theoretically explore hyperbolic magnetoexciton polaritons (HMEPs) in van der Waals crystals of WTe2, MoS2, and phosphorene. Based on the Shubnikov-de Haas effect, canalized HMEPs with ultralow group velocity (~10-5…

Extremely diverse coronal jets accompanying an erupting filament captured by Solar Orbiter
Solar jets are collimated plasma ejections driven by magnetic reconnection, which play a critical role in the energy release and mass transport in the solar atmosphere. Using Solar Orbiter's Extreme Ultraviolet Imager (EUI) with its unprecedented spatiotemporal resolution, we report the discovery of nine transient coronal jets associated with a filament eruption on September 30, 2024. These jets, with a median lifetime of only 22 seconds, have significantly shorter timescales than previously ob…

PeV particle acceleration and non-thermal emission in the `minimalist' model of the extended jets in W50/SS433
The W50 nebula around microquasar SS~433, powered by supercritical accretion, features two `extended jets' (tens of pc long and a few pc wide) from which polarized X-ray and very high energy radiation above 100 TeV is detected. Here we present a model of very high energy particle acceleration in these extended jets. In the `minimalist' model (discussed in Churazov, Khabibullin, and Bykov, 2024), a collimated outflow aligned with the rotation axis is propagating through a more isotropic wind pro…

Jet MHD analytical model - framework for radiative transfer
We developed the full magnetohydrodynamical analytical jet model that allows accurate reproducing of a transversal and longitudinal structure for a highly collimated relativistic jets. This model can be used as a setup for convenient solution of radiative transfer equations and modelling the total intensity and polarization maps. We show that the analytical fits are in excellent agreement with the numerical solutions of full magnetohydrodynamical equations. Our approach allows setting easily di…

The Integrating Miniature Piggyback for Impulsive Solar Hard X-rays (IMPISH): a spectrometer for the GRIPS-2 balloon campaign
The Integrating Miniature Piggyback for Impulsive Solar Hard X-rays (IMPISH) is a piggyback mission originally designed for the second flight of the Gamma-Ray Imager/Polarimeter for Solar flares (GRIPS-2) Antarctic balloon. IMPISH will take measurements of collimated, full-Sun X-ray spectra with the goal of detecting sub-second variations (order of tens of milliseconds) of nonthermal X-ray emission during the impulsive phase of large solar flares to probe particle acceleration mechanisms driven…

Radiation magnetohydrodynamics modeling of an impulsively driven chromospheric jet in the solar atmosphere
In this paper, we present a numerical simulation of an impulsively driven chromospheric jet in the solar atmosphere using the non-ideal magnetohydrodynamic (MHD) equations coupled with frequency- and angle-averaged radiation transport equations. These include the dynamics of the radiation energy density and radiation flux. The jet is initiated by a localized Gaussian pulse applied to the vertical velocity component in the upper chromosphere (y = 1.75 Mm), producing a collimated plasma structure…

Late-afterglow Emission from a Quasi-spherical Outflow in a stratified environment
Gamma-ray bursts (GRBs) are cosmic events occurring at large distances beyond our galaxy. They provide a unique opportunity to study electromagnetic patterns not seen elsewhere. When the collimated GRB outflow interacts with the outer layers of a star or the wind generated by a binary neutron star merger, it releases energy, forming a quasi-spherical outflow around it. This broad outflow begins to radiate once it has transferred enough energy to the surrounding medium. We have developed a new a…
