How Robust is the Cosmic Distance with Tip of Red Giant Branch against Stellar Population Variations?
Chul Chung, Young-Wook Lee, Suk-Jin Yoon +10
The tip of the red giant branch (TRGB) provides a key standard candle for extragalactic distance measurements and for refining the Hubble constant. We test its robustness by quanti…

Comparison of MOND and Verlinde's emergent gravity in dwarf spheroidals
Youngsub Yoon, Sanghyeon Han, Ho Seong Hwang
We apply Modified Newtonian Dynamics (MOND) and Verlinde's emergent gravity separately to calculate the radial accelerations in 23 dwarf spheroidals. Then, we compare them with the…
