HALO I: Photometric continuum reverberation mapping of Fairall 9
Amit Kumar Mandal, Francisco Pozo Nuñez, Vikram Kumar Jaiswal +23
We investigate the origin of inter-band continuum time delays in active galactic nuclei (AGNs) to study the structure and properties of their accretion disks. We aim to measure the…

Secondary standards in the UKIRT faint standard fields
Marek Górski, Grzegorz Pietrzyński, Paulina Karczmarek +8
We present precise J- and K-band photometric measurements for 128 near-infrared secondary standard stars, located in the 19 UKIRT/MKO primary faint standard fields. The data were c…

Precise physical parameters of three late-type eclipsing binary giant stars in the Large Magellanic Cloud
G. Rojas García, D. Graczyk, G. Pietrzyński +17
Detached eclipsing binaries (DEBs) allow for the possibility of precise characterization of its stellar components. They offer a unique opportunity to derive their physical paramet…
