Understanding pulsar magnetospheres with the SKAO

L. S. Oswald, A. Basu, M. Chakraborty +22

The SKA telescopes will bring unparalleled sensitivity across a broad radio band, a wide field of view across the Southern sky, and the capacity for sub-arraying, all of which make…

An outflow from the X-ray corona as the origin of millimeter emission from radio-quiet AGN

A. Hankla, A. Philippov, R. Mbarek +4

Recent observations of radio-quiet active galactic nuclei (RQAGN) have shown the presence of millimeter emission, whose origin remains unknown, from within parsec scales of the cen…

First Mid-infrared Detection and Modeling of a Flare from Sgr A*. II. Mid-IR Spectral Energy Distribution and Millimeter Polarimetry

Joseph M. Michail, Sebastiano D. von Fellenberg, Garrett K. Keating +20

S. D. von Fellenberg et al. (2025a, Paper I) reported the first mid-infrared detection of a flare from Sgr A*. The JWST/MIRI/MRS observations were consistent with an orbiting hotsp…

First mid-infrared detection and modeling of a flare from Sgr A*

Sebastiano D. von Fellenberg, Tamojeet Roychowdhury, Joseph M. Michail +24

The time-variable emission from the accretion flow of Sgr A*, the supermassive black hole at the Galactic Center, has long been examined in the radio-to-mm, near-infrared (NIR), an…

Multi-wavelength observations of a jet launch in real time from the post-changing-look Active Galaxy 1ES 1927+654

Sibasish Laha, Eileen T. Meyer, Dev R. Sadaula +34

We present results from a high cadence multi-wavelength observational campaign of the enigmatic changing look AGN 1ES 1927+654 from May 2022- April 2024, coincident with an unprece…
