Determination of the Local Hubble Constant from Virgo Infall Using TRGB Distances
Yoo Jung Kim, Jisu Kang, Myung Gyoon Lee +1
An independent determination of is crucial given the growing tension between the Hubble constant, , derived locally and that determined from the modeling of the cosmic m…
The Carnegie-Chicago Hubble Program. IX. Calibration of the Tip of the Red Giant Branch Method in the Mega-Maser Host Galaxy, NGC4258 (M106)
In Sung Jang, Taylor Hoyt, Rachael Beaton +7
In the nearby galaxy NGC 4258, the well-modeled orbital motion of HO masers about its supermassive black hole provides the means to measure a precise geometric distance. As a r…
A New Metal-poor Globular Cluster and Resolved Stars in the Outer Disk of the Black Eye Galaxy M64: Implication for the Origin of the Type III Disk Break
Jisu Kang, Yoo Jung Kim, Myung Gyoon Lee +1
M64 is a nearby spiral galaxy with a Type III anti-truncation component. To trace the origin of the Type III component, we present Hubble Space Telescope/Advanced Camera for Survey…
The Nature of Ultra-diffuse Galaxies in Distant Massive Galaxy Clusters: Abell 370 in the Hubble Frontier Fields
Jeong Hwan Lee, Jisu Kang, Myung Gyoon Lee +1
We report the discovery of ultra-diffuse galaxies (UDGs) in Abell 370 (). We find 46 UDGs in Abell 370 from the images of the Hubble Frontier Fields (HFF). Most UDGs are l…
Calibration of the Tip of the Red Giant Branch (TRGB)
Wendy L. Freedman, Barry F. Madore, Taylor Hoyt +6
The Tip of the Red Giant (TRGB) method provides one of the most accurate and precise means of measuring the distances to nearby galaxies. Here we present a VIJHK absolute calibrati…
