HALO II: Constraining Hubble constant through continuum delay fitting of Fairall 9
Amit Kumar Mandal, Francisco Pozo Nuñez, Vikram Kumar Jaiswal +28
The Hubble tension remains one of the most significant unresolved problems in modern cosmology. A key question is whether it may arise from underestimated systematic uncertainties…
Confirming new changing--look AGNs discovered through optical variability using a random-forest based light curve classifier
E. López-Navas, M. L. Martínez-Aldama, S. Bernal +6
Determining the frequency and duration of changing--look (CL) active galactic nuclei (AGNs) phenomena, where the optical broad emission lines appear or disappear, is crucial to und…
Dark energy constraints from quasar observations
B. Czerny, M. L. Martínez-Aldama, G. Wojtkowska +9
Recent measurements of the parameters of the Concordance Cosmology Model (CDM) done in the low-redshift Universe with Supernovae Ia/Cepheids, and in the distant Universe done wi…
The CaFe Project: Optical Fe II and Near-Infrared Ca II triplet emission in active galaxies: (I) Photoionization modelling
Swayamtrupta Panda, Mary Loli Martínez-Aldama, Murilo Marinello +3
Optical Fe II emission is a strong feature in quasar spectra originating in the broad-line region (BLR). The difficulty in understanding the complex Fe II pseudo-continuum has led…
Quasars from LSST as dark energy tracers: first steps
Mary Loli Martínez-Aldama, Swayamtrupta Panda, Bożena Czerny +1
In the near future, new surveys promise a significant increase in the number of quasars (QSO) at large redshifts. This will help to constrain the dark energy models using quasars.…
