We report the results of a multiband observing campaign on the famous blazar 3C 279
conducted during a phase of increased activity from 2013 December to 2014 April, including …

We report on our study of the supernova (SN) 2022xxf based on observations obtained
during the first four months of its evolution. The light curves (LCs) display two humps of …

We present early phase observations in optical and near-infrared wavelengths for the
extremely luminous Type Ia supernova (SN Ia) 2009dc. The decline rate of the light curve is …

Context. Over the past few years, on several occasions, large, continuous rotations of the
electric vector position angle (EVPA) of linearly polarized optical emission from blazars have …

由于大气及地物光谱辐射的偏振敏感性, 使得可见和红外偏振遥感逐步发展成为地基,
航空和卫星观测的新技术手段, 在全球气候变迁研究, 对地遥感和天文研究等领域得到应用 …

We present a systematic study of the most luminous (M IR [Vega magnitudes] brighter than−
14) infrared (IR) transients discovered by the SPitzer InfraRed Intensive Transients Survey …

We present the results of a series of radio, optical, X-ray, and γ-ray observations of the BL
Lac object S50716+ 714 carried out between April 2007 and January 2011. The …

Blazars are highly variable active galactic nuclei that emit radiation at all wavelengths from
radio to gamma rays. Polarized radiation from blazars is one key piece of evidence for …

We present optical, near-infrared, and radio observations of supernova (SN) SN IIb 2022crv.
We show that it retained a very thin H envelope and transitioned from an SN IIb to an SN Ib; …

In this Letter we report a discovery of a prominent flash of a peculiar overluminous Type Ia
supernova, SN 2020hvf, in about 5 hr of the supernova explosion by the first wide-field …
