RR Lyrae stars with variable mean magnitudes
Gergely Hajdu, Johanna Jurcsik, Márcio Catelan +6
Context. A number of RR Lyrae stars show variable mean magnitudes in the OGLE survey light curves of the Galactic bulge. Hitherto this phenomenon was not studied, as it was general…
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…
CAPOS: The bulge Cluster APOgee Survey XI. Unraveling the chemical composition of the bulge globular cluster NGC 6304
Carolina Montecinos, Doug Geisler, Cesar Muñoz +1
Context. With CAPOS, we can mitigate the observational difficulties limiting access to bulge globular clusters in the optical and investigate them in more detail in the near-IR. Ai…
Distance to the Globular Cluster M 3 from the Infrared Surface Brightness Technique applied to RR Lyrae stars
Bartłomiej Zgirski, Wolfgang Gieren, Grzegorz Pietrzyński +10
The Infrared Surface Brightness (IRSB) technique is a specific application of the Baade-Wesselink method. Given a proper calibration, well covered optical and near-infrared photome…
Brazilian Twin Photons 32nd anniversary
Renné Medeiros de Araújo, Raphael César Souza Pimenta, Lucas Marques Fagundes +4
We present a historical review of the development and impact of spontaneous parametric down-conversion (SPDC) in Brazil, marking over three decades since the first twin-photon expe…
On the regularity for thermoelastic systems of phase-lag parabolic type
Jaime Muñoz Rivera, Elena Ochoa Ochoa, Ramón Quintanilla
In this article, we investigate the maximal smoothness (infinite differentiability) of solutions to thermoelastic models, specifically those where the heat equation is of the ``pha…
