A clear detection of proper motion confirms that the claimed galaxy candidate, "Capotauro'', is a Y-type brown dwarf
F. -Y. F. Liu, D. J. McLeod, B. J. Sutlieff +13
The compact red source ``Capotauro'', discovered in deep JWST imaging in 2025, has been suggested as a possible galaxy candidate at redshift on account of its extreme N…
Multi-band optical photometric variability of the blazar OJ 287 from 2015 to 2025
Alok C. Gupta, Karan Dogra, Mark Kidger +101
We present the most densely sampled multi-band optical photometric observations of the peculiar BL Lacertae object OJ 287 from 2015 to 2025 with a focus on its optical activity on…
Simultaneous Multi-band Optical Follow-up Observations of a Gamma-Ray Flare in BL Lacertae
X. Chang, D. R. Xiong, Chenxu Liu +17
On October , BL Lacertae () experienced one of its brightest gamma-ray flares. We conducted simultaneous follow-up observations in the , , , , ,…
A new wideband radio polarization observation of the Supernova Remnant G315.42.3
X. Chen, X. Sun, J. F. Kaczmarek +3
The supernova remnant (SNR) G315.42.3 (MSH 1463 or RCW 86) exhibits strong emission across the electromagnetic spectrum. Radio polarization observations probe magnetic fields…
A sudden dramatic change and recovery of magneto-environment of a repeating fast radio burst
Y. Li, S. B. Zhang, Y. P. Yang +35
Fast radio bursts (FRBs) are millisecond-duration radio bursts with unidentified extra-galactic origin. Some FRBs exhibit mild magneto-ionic environmental variations, possibly attr…
Decadal evolution of a repeating fast radio burst source
P. Wang, J. S. Zhang, Y. P. Yang +48
The origin of fast radio bursts (FRBs), the brightest cosmic radio explosions, is still unknown. Bearing critical clues to FRBs' origin, the long-term evolution of FRBs has yet to…
