ABSTRACT Background The COVID‐19 pandemic has reshaped the landscape of respiratory viral infections globally. This study examines these changes on Reunion Island, a French department in the southeastern Indian Ocean. Methods Retrospective data from 2017 to 2023, from over 24,000 samples collected across the hospital system, partner laboratories, and a

Binary Cepheids from optical interferometry
Classical Cepheid stars have been considered since more than a century as reliable tools to estimate distances in the universe thanks to their Period-Luminosity (P-L) relationship.

Recently, a double-lined binary classical Cepheid, OGLE-LMC-CEP-1347, was discovered with the orbital period ( P _orb = 59 days), 5 times shorter than that of any binary Cepheid known before.

NEW ASPECT OF SMALL-AMPLITUDE CEPHEID SU CAS
New 17 high-resolutional spectra of small-amplitude Cepheid SU Cas have been obtained to determine its atmosphere parameters (Teff=6353 K; log g=2.38; Vt=3.25 km s -1 and to measure its radial velocities.

We present the first gri -band period–luminosity (PL) and period–Wesenheit (PW) relations for the fundamental mode anomalous Cepheids. These PL and PW relations were derived from a combined sample of five anomalous Cepheids in globular cluster M92 and ...

Breast cancer presents a significant risk to public health and is the primary cause of cancer‐related death in women. Awareness of metastatic breast cancer (mBC) continues to increase, and advances have been made; however, challenges remain for many patient populations that do not receive equal opportunities along the treatment pathway. The Underserved

We present a distance determination to the Small Magellanic Cloud (SMC) using optical and near-infrared photometry from OGLE and IRSF. Applying a multiband method to V, I, J, H and K OGLE and IRSF data, we measured the SMC true distance modulus and mean ...

Cepheid variables in the LMC cluster NGC 1866. I. New BVRI CCD photometry
We report BV(RI)c CCD photometric data for a group of seven Cepheid variables in the young, rich cluster NGC 1866 in the Large Magellanic Cloud. The photometry was obtained as part of a program to determine accurate distances to these Cepheids by means ...

Prospects for X-Ray and FUV Observations to Provide Insight Into the “Cepheid Mass Problem”
The classical Cepheid Leavitt Law (Period-Luminosity relation) has been known for 100 years, and used in extragalactic distance determination for nearly as long.
