A rare sextuple-merging brightest cluster galaxy system in a disturbed galaxy cluster observed with the Einstein Probe Follow-up X-ray Telescope

Z. L. Wen, S. M. Jia, Z. S. Yuan +12

The evolutionary processes of galaxy clusters influence the properties of their member galaxies. We present a joint X-ray--optical analysis of the galaxy cluster WHY J050106.2+0137…

IceCube Real-time Searches for High-energy Neutrinos Coincident with LIGO/Virgo/KAGRA Gravitational-Wave Alerts in O4a

The IceCube Collaboration, R. Abbasi, M. Ackermann +418

Gravitational-wave events from mergers of compact objects are a predicted source of high-energy neutrinos. Using data from the IceCube Neutrino Observatory, we search for neutrinos…

JOYS+ analyses of OCN, NO, NO, and complex cyanides in ices -- Thermal processing results in modest enhancement of OCN ice

P. Nazari, N. Brunken, Y. Chen +12

Nitrogen-bearing molecules are more difficult to observe than oxygen-bearing ones, mainly due to the lower abundance of nitrogen in the interstellar medium. Therefore, the formatio…

JOYS: Linking the molecular ice and gas-phase composition towards the high-mass hot core IRAS 18089-1732

C. Gieser, W. R. M. Rocha, Y. Chen +11

Context. The formation and destruction of molecules in the interstellar medium is a complex interplay between gas-phase reactions as well as processes on grain surfaces and within…

Unlocking accretion rate diagnostics for high-mass protostars using JWST/MIRI HI lines

S. D. Reyes-Reyes, H. Beuther, E. F. van Dishoeck +14

While many aspects of high-mass star formation have been investigated, the accretion onto the central protostars is one of the most fundamental but less explored physical propertie…

Sulfur oxides tracing streamers and shocks at low mass protostellar disk-envelope interfaces

X. -C. Liu, E. F. van Dishoeck, M. R. Hogerheijde +8

Accretion shocks are thought to play a crucial role in the early stages of star and planet formation, but their direct observational evidence remains elusive, particularly regardin…
