Cause of chromospheric opposite polarity intrusions discovered in Sunrise III/SCIP data: MURaM-ChE simulations point to twisted flux ropes
Patrick A. Ondratschek, Damien F. Przybylski, Robert H. Cameron +33
The Sunrise Chromospheric Infrared spectroPolarimeter (SCIP) instrument onboard the balloon-borne Sunrise III observatory provided new high-resolution observations of the solar chr…
Running Hubble Constant with the Redshift as a Marker of Evolutionary Dark Energy
Nakia Carlevaro, Giovanni Montani, Maria Giovanna Dainotti
We discuss the interpretation of an observed running Hubble constant with the redshift, in terms of the possible underlying physical scenario. Assuming, like in the CDM model, t…
Science operation, data handling, and ground support system of the SOLAR-C mission
Shin Toriumi, Mari Nishiyama, Keiichi Matsuzaki +16
SOLAR-C is an international solar-observing satellite mission led by Japan Aerospace Exploration Agency (JAXA). It aims to elucidate mass and energy transport in solar atmospheres…
An Eccentric Massive Protobinary Assembled via a Core-merger Parabolic Encounter
Yao Wang, Yichen Zhang, Rubén Fedriani +14
Most massive stars form in binary systems, which profoundly influence their subsequent evolution. However, how such systems form remains poorly understood, with several competing s…
Magnetic Fields in Massive Star-forming Regions (MagMaR). IX. Radiative Torque Alignment and Disruption in NGC6334I
Vineet Rawat, Thiem Hoang, Patricio Sanhueza +18
Intense radiation from high-mass stars is expected to significantly affect dust grain alignment and evolution through RAdiative Torques (RATs). We investigate this effect in a mass…
H I Absorbers as Beacons of Hidden Structure at : Multi-Component, Metal-Rich Absorption System near a Protocluster
Kentaro Koretomo, Nobunari Kashikawa, Toru Misawa +12
H I gas traces the large-scale structure and provides the primary fuel for star formation. High- protoclusters are ideal laboratories to study how H I gas is accreted and consum…
Systematic and Statistical Properties of Prominence Eruptions on the M-dwarf YZ CMi
Yuto Kajikiya, Kosuke Namekata, Yuta Notsu +4
M-dwarfs produce frequent flares, and their associated mass ejections are expected to significantly affect the habitability of close-in exoplanets. Recent spectroscopic observation…
ACES VII. Compact Continuum Source Catalog of the Central Molecular Zone
Jennifer Wallace, Cara Battersby, Nazar Budaiev +58
The Central Molecular Zone (CMZ) resides in the inner few hundred parsecs of our Galaxy, and despite being the largest reservoir of dense molecular gas in the Milky Way, it has a r…
AO3k + SCExAO: on-sky wavefront quality and demonstration of novel WFS techniques with the double XAO system
Julien Lozi, Kyohoon Ahn, Vincent Deo +5
The Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) system, fed by its upstream 3000-actuator "woofer" (AO3k), serves both as a platform for high contrast imaging (HCI) techn…
Synchrotron self-Compton Reverse Shock in Energy-Injection and Radiative Scenarios
Fraija Nissim, Betancourt-Kamenetskaia Boris, Galván Antonio +1
Gamma-ray bursts (GRBs) are among the most energetic extragalactic transients, providing a unique laboratory to investigate the physical origin of the diverse morphologies observed…
Forward modelling coronagraphic images with a fully physical, differentiable digital twin of MagAO-X: first laboratory results
Matthijs Mars, Sebastiaan Y. Haffert, Louis Desdoigts +10
Post-processing of high contrast imaging data relies on an accurate model of the stellar point spread function (PSF). Current techniques build this model from the science images th…
