KIC 6464285: A Solar-type Eclipsing Binary in a Hierarchical Triple System with Quasi-periodic Out-of-eclipse Modulations
Fang-Bin Meng, Li-Ying Zhu, Sheng-Bang Qian +10
We present the first detailed analysis of the solar-type triple system KIC 6464285. Combining long-term, high-precision photometry from Kepler, TESS, and ZTF with low-resolution sp…
TDCOSMO XXV: Measuring H0 to 6.5% precision with quasar strong lensing and maximally flexible mass-sheet dynamics
William Sheu, Tommaso Treu, Martin Millon +16
We present a blind time-delay cosmography measurement of the Hubble-Lemaître constant based on the quadruply imaged quasar SDSSJ1433+6007. Our analysis combines deep Hubble S…
IY Lyr: A Thick-Disk first-overtone RR Lyrae Star with a Possible Neutron Star Companion
Linjia Li, Shengbang Qian, Ildar Asfandiyarov +10
IY Lyr, historically misclassified as an eclipsing binary, has been previously identified as a first-overtone RR Lyrae star (RRc star). Using multiband photometry (All-Sky Automate…
HOLISMOKES XIX: SN 2025wny at , the first strongly lensed superluminous supernova
Stefan Taubenberger, Ana Acebron, Raoul Cañameras +45
We present imaging and spectroscopic observations of supernova SN 2025wny, associated with the lens candidate PS1 J0716+3821. Photometric monitoring from the Lulin and Maidanak obs…
CSS_J154915.7+375506: A low-mass-ratio marginal contact binary system with a hierarchical third body
Jin-Feng Wu, Li-Ying Zhu, Azizbek Matekov +6
We presented the multi-filter light curves of CSS_J154915.7+375506 inaugurally, which were observed by the 1.5 m AZT-22 telescope at Maidanak Astronomical Observatory. A low-resolu…
The Stellar Abundances and Galactic Evolution Survey (SAGES) -- -- I. General Description and the First Data Release (DR1)
Zhou Fan, Gang Zhao, Wei Wang +35
The Stellar Abundances and Galactic Evolution Survey (SAGES) of the northern sky is a specifically-designed multi-band photometric survey aiming to provide reliable stellar paramet…
Liverpool-Maidanak monitoring of the Einstein Cross in 20062019. I. Light curves in the optical bands and microlensing signatures
L. J. Goicoechea, B. P. Artamonov, V. N. Shalyapin +8
Quasar microlensing offers a unique opportunity to resolve tiny sources in distant active galactic nuclei and study compact object populations in lensing galaxies. We therefore sea…
COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses XIV. Time delay of the doubly lensed quasar SDSS J1001+5027
S. Rathna Kumar, M. Tewes, C. S. Stalin +8
This paper presents optical R-band light curves and the time delay of the doubly imaged gravitationally lensed quasar SDSS J1001+5027 at a redshift of 1.838. We have observed this…
COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses XII. Time delays of the doubly lensed quasars SDSS J1206+4332 and HS 2209+1914
E. Eulaers, M. Tewes, P. Magain +8
Aims. Within the framework of the COSMOGRAIL collaboration we present 7- and 8.5-year-long light curves and time-delay estimates for two gravitationally lensed quasars: SDSS J1206+…
COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses IX. Time delays, lens dynamics and baryonic fraction in HE 0435-1223
F. Courbin, V. Chantry, Y. Revaz +13
We present accurate time delays for the quadruply imaged quasar HE 0435-1223. The delays were measured from 575 independent photometric points obtained in the R-band between Januar…
The WEBT Campaign on the Blazar 3C279 in 2006
M. Boettcher
The quasar 3C279 was the target of an extensive multiwavelength monitoring campaign from January through April 2006, including an optical-IR-radio monitoring campaign by the Whole…
COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses V. The time delay in SDSS J1650+4251
C. Vuissoz, F. Courbin, D. Sluse +8
Aims: Our aim is to measure the time delay between the two gravitationally lensed images of the z = 1.547 quasar SDSS J1650+4251, in order to estimate the Hubble constant H_0. Meth…
The WEBT BL Lacertae Campaign 2001 and its extension
M. Villata, C. M. Raiteri
BL Lacertae has been the target of four observing campaigns by the Whole Earth Blazar Telescope (WEBT) collaboration. In this paper we present light curves obtained by the…
