A 1% distance to the Large Magellanic Cloud measured by population-II pulsating stars using Gaia Data Release 3
Bastian Lengen, Richard I. Anderson, Mauricio Cruz Reyes
Population-II pulsating stars provide a route to extragalactic distances that is independent of the classical Cepheid distance scale and complementary to geometric and tip-of-the-r…
Calibrating the Tip of the Red Giant Branch and measuring Magellanic Cloud distances to 2% exclusively with Gaia
Mauricio Cruz Reyes, Richard I. Anderson, Bastian Lengen
We have calibrated the Tip of the Red Giant Branch (TRGB) using our recent catalog of homogeneous, high-accuracy Globular Cluster (GC) distances. The GC distances were determined b…
The Local Distance Network: a community consensus report on the measurement of the Hubble constant at 1% precision
H0DN Collaboration, Stefano Casertano, Gagandeep Anand +35
The direct, empirical determination of the local value of the Hubble constant (H0) has markedly advanced thanks to improved instrumentation, measurement techniques, and distance es…
A joint 1% calibration of the RR Lyrae & type-II Cepheid Leavitt laws yields homogeneous distances to 93 Galactic globular clusters
Bastian Lengen, Richard I. Anderson, Mauricio Cruz Reyes +1
Recent work has established large samples of astrometrically confirmed RR Lyrae and type-II Cepheid members of Galactic globular clusters (GCs). Any given GC can contain multiple s…
Variable stars in Galactic globular clusters II. Population II Cepheids
Mauricio Cruz Reyes, Richard I. Anderson, Susmita Das
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 Cephe…
Relation between the geometric shape and rotation of Galactic globular clusters
Mauricio Cruz Reyes, Richard I. Anderson
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…
VELOcities of CEpheids (VELOCE) I. High-precision radial velocities of Cepheids
Richard I. Anderson, Giordano Viviani, Shreeya S. Shetye +27
This first VELOCE data release comprises 18,225 high-precision RV measurements of 258 bona fide classical Cepheids on both hemispheres collected mainly between 2010 and 2022, along…
Variable stars in galactic globular Clusters I. The population of RR Lyrae stars
Mauricio Cruz Reyes, Richard I. Anderson, Lucas Johansson +2
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-over…
