TL;DR
This study measures the supermassive black hole masses in two brightest cluster galaxies using Hubble Space Telescope data, providing key insights into galaxy evolution and black hole scaling relations.
Contribution
It presents new black hole mass measurements for Abell 1836-BCG and Abell 3565-BCG based on detailed photometric and kinematic modeling.
Findings
Black hole mass in Abell 1836-BCG: 4.8(+0.8,-0.7) x 10^9 M_sun
Black hole mass in Abell 3565-BCG: 1.3(+0.3,-0.4) x 10^9 M_sun
Results support existing black hole scaling relations.
Abstract
Two brightest cluster galaxies (BCGs), namely Abell 1836-BCG and Abell 3565-BCG, were observed with the Advanced Camera for Surveys (ACS) and the Space Telescope Imaging Spectrograph (STIS) on board the Hubble Space Telescope. By modeling the available photometric and kinematic data, it resulted that the mass of Abell 1836-BCG and Abell 3565-BCG are M_bh=4.8(+0.8,-0.7)x10^9 M_sun and M_bh=1.3(+0.3,-0.4)x10^9 M_sun at 1 sigma confidence level, respectively.
