In the Eye of the Storm: The Third Giant X-ray Outburst of the Extreme Changing-look AGN IC 3599
D. Grupe, S. Komossa, W. Zheng +10
We report the discovery and multiwavelength follow-up observations of a giant (factor >100) X-ray outburst of the exceptional changing-look active galactic nucleus (AGN) IC 3599. T…
SN 2023ixf in the Pinwheel Galaxy M101: From Shock Breakout to the Nebular Phase
Weikang Zheng, Luc Dessart, Alexei V. Filippenko +39
We present photometric and spectroscopic observations of SN 2023ixf covering from day one to 442 days after explosion. SN 2023ixf reached a peak -band absolute magnitude of $-18…
Evolution of Neptune at Near-Infrared Wavelengths from 1994 through 2022
Erandi Chavez, Imke de Pater, Erin Redwing +15
Using archival near-infrared observations from the Keck and Lick Observatories and the Hubble Space Telescope, we document the evolution of Neptune's cloud activity from 1994 to 20…
SN 2023ixf in Messier 101: Photo-ionization of Dense, Close-in Circumstellar Material in a Nearby Type II Supernova
W. V. Jacobson-Galan, L. Dessart, R. Margutti +65
We present UV/optical observations and models of supernova (SN) 2023ixf, a type II SN located in Messier 101 at 6.9 Mpc. Early-time ("flash") spectroscopy of SN 2023ixf, obtained p…
Analysis of Neptune's 2017 Bright Equatorial Storm
Edward Molter, Imke de Pater, Statia Luszcz-Cook +22
We report the discovery of a large (8500 km diameter) infrared-bright storm at Neptune's equator in June 2017. We tracked the storm over a period of 7 months with high-cadenc…
Giant Metrewave Radio Telescope detection of associated HI 21cm absorption at towards TXS1954+513
J. N. H. S. Aditya, Nissim Kanekar, J. Xavier Prochaska +3
We have used the 610 MHz receivers of the Giant Metrewave Radio Telescope (GMRT) to detect associated HI 21cm absorption from the blazar TXS1954+513. The GMRT HI 21cm…
