Identifying Decaying Supermassive Black Hole Binaries from their Variable Electromagnetic Emission
Zoltán Haiman, Bence Kocsis, Kristen Menou +2
Supermassive black hole binaries (SMBHBs) with masses in the range 10^4-10^7 M_sun/(1+z), produced in galaxy mergers, are thought to complete their coalescence due to the emission…
Prompt Shocks in the Gas Disk Around a Recoiling Supermassive Black Hole Binary
Zoltan Lippai, Zsolt Frei, Zoltan Haiman
Supermassive black hole binaries (BHBs) produced in galaxy mergers recoil at the time of their coalescence due to the emission of gravitational waves (GWs). We simulate the respons…
Finding the Electromagnetic Counterparts of Cosmological Standard Sirens
B. Kocsis, Z. Frei, Z. Haiman +1
The gravitational waves (GW) emitted during the coalescence of supermassive black holes (SMBHs) in the mass range 10^4-10^7 M_sun will be detectable out to high redshifts with LISA…
Can Virialization Shocks be Detected Around Galaxy Clusters Through the Sunyaev-Zel'dovich Effect?
Bence Kocsis, Zoltan Haiman, Zsolt Frei
In cosmological structure formation models, massive non-linear objects in the process of formation, such as galaxy clusters, are surrounded by large-scale shocks at or around the e…
Semi-automatic Removal of Foreground Stars from Images of Galaxies
Zsolt Frei
A new procedure, designed to remove foreground stars from galaxy profiles is presented. Although several programs exist for stellar and faint object photometry, none of them treat…
A Catalog of Digital Images of 113 Nearby Galaxies
Zsolt Frei, Puragra Guhathakurta, James E. Gunn +1
We present a digital catalog of images of 113 galaxies in this paper. These galaxies are all nearby, bright, large and well resolved. All images were recorded with charge coupled d…
