VELOcities of CEpheids (VELOCE): I. High-precision radial velocities of Cepheids

Vivien François Bonvin, Mauricio Cruz Reyes, Giordano Viviani, Saniya Khan, Henryka Ewa Netzel, Shreeya Sushil Shetye, Zoi Tzogia Spetsieri

We present the first data release of VELOcities of CEpheids (VELOCE), dedicated to measuring the high-precision radial velocities (RVs) of Galactic classical Cepheids (henceforth, Cepheids). The first data release (VELOCE DR1) comprises 18 225 RV measureme ...

Absolute calibration of standard candles in the Gaia era

Mauricio Cruz Reyes

Measuring the distance to stars in relation to us is fundamental for understanding the universe we live in, however, it is also one of the most challenging tasks in astronomy. Accurately estimating distances would allow us to understand the distribution of ...

A 0.9% calibration of the Galactic Cepheid luminosity scale based on Gaia DR3 data of open clusters and Cepheids

Richard Irving Anderson, Mauricio Cruz Reyes

We have conducted a search for open clusters in the vicinity of classical Galactic Cepheids based on high-quality astrometry from the third data release (DR3) of the ESA mission Gaia to improve the calibration of the Leavitt law (LL). Our approach requires ...

Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry

Richard Irving Anderson, Mauricio Cruz Reyes

Context. Gravitational waves from black-hole (BH) merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected based on most stellar evolution models-And also higher than known ...

Relation between the geometric shape and rotation of Galactic globular clusters

Richard Irving Anderson, Mauricio Cruz Reyes

We homogeneously measured the elliptical shapes of 163 globular clusters (GCs) using the on-sky distribution of their cluster members and the third data release of the ESA mission Gaia (DR3). The astrometry enables the differentiation of stars within clust ...

Cluster Cepheids with High Precision Gaia Parallaxes, Low Zero-point Uncertainties, and Hubble Space Telescope Photometry

Richard Irving Anderson, Mauricio Cruz Reyes

We present Hubble Space Telescope (HST) photometry of 17 Cepheids in open clusters and their cluster mean parallaxes from Gaia EDR3. These parallaxes are more precise than those from individual Cepheids (G < 8 mag) previously used to measure the Hubble con ...

Variable stars in Galactic globular clusters: II. Population II Cepheids

Richard Irving Anderson, Mauricio Cruz Reyes

We identified a sample of 88 bona fide Population II Cepheids (henceforth referred to as Cepheids) and 44 candidates in Galactic globular clusters (GCs). Seventy-eight of the Cepheids in the sample align within 2 sigma of the period-luminosity relation for ...

On the Degeneracy between f sigma(8) Tension and Its Gaussian Process Forecasting

Mauricio Cruz Reyes

In this Article, we reconstruct the growth and evolution of the cosmic structure of the Universe using Markov chain Monte Carlo algorithms for Gaussian processes. We estimate the difference between the reconstructions that are calculated through a maximiza ...

Variable stars in galactic globular clusters I. The population of RR Lyrae stars

Zoé Lisa Medaric, Richard Irving Anderson, Mauricio Cruz Reyes, Henryka Ewa Netzel

We present a comprehensive catalog of 2824 RR Lyrae stars (RRLs) residing in 115 Galactic globular clusters (GCs). Our catalog includes 1594 fundamental-mode (RRab), 824 first-overtone (RRc), and 28 double-mode (RRd) RRLs, as well as 378 RRLs of an unknown ...
