This image shows an ongoing merger between two simulated galaxies, which will lead to the formation of a massive black hole binary. This image was produced using a cosmological simulation of galaxy formation, through stellar population synthesis and dust radiative transfer. We are using these synthetic telescope images to study the unique morphological properties of the host galaxies of massive black hole mergers.

The blackbody continuum has broad absorption features due to the opacity of freshly-synthesized r-process elements in the kilonova ejecta. We fit the observed spectra to synthetic spectra from radiative transfer simulations of kilonova ejecta, to infer the abundance pattern of r-process elements produced in this merger (Vieira et al., 2023).

The X-ray afterglow surprisingly brightened over several months after the merger, unlike any other short Gamma-ray burst afterglow ever observed (Ruan et al., 2018).

Our systematic tiling approach using a wide-field optical imager on a 3m-class telescope is well-suited for the more-distant mergers expected to be detected by LIGO/Virgo in Observing Run 4. https://gamma-research.space/research-program/clquasars monthly 0.5 2025-08-05 https://gamma-research.space/new-page daily 0.75 2020-12-19 https://gamma-research.space/home daily 1.0 2025-04-30 https://gamma-research.space/the-team daily 0.75 2025-11-02 https://images.squarespace-cdn.com/content/v1/5fdc70dff65a9a5fd491b52a/6428be26-6d9c-4041-863b-7483c6b48303/virginia.jpg The Team https://images.squarespace-cdn.com/content/v1/5fdc70dff65a9a5fd491b52a/5a312418-f7b0-466b-a60b-db60f48515fd/Sam.jpg The Team https://images.squarespace-cdn.com/content/v1/5fdc70dff65a9a5fd491b52a/400a56cb-94f8-4173-81da-0736a51bc4da/Jaeden-Bardati_600.jpg The Team https://images.squarespace-cdn.com/content/v1/5fdc70dff65a9a5fd491b52a/7feb087f-7efd-40dc-98c0-8114e18a94b7/nicole.jpg The Team https://images.squarespace-cdn.com/content/v1/5fdc70dff65a9a5fd491b52a/b8623c26-7e33-4d97-909b-bf3049d4b83b/wx.png The Team https://images.squarespace-cdn.com/content/v1/5fdc70dff65a9a5fd491b52a/8e01224c-c912-4422-ae78-bc38d4eaeed8/patrick.png The Team https://images.squarespace-cdn.com/content/v1/5fdc70dff65a9a5fd491b52a/2187770c-d57a-4a4d-947b-7c84dd098da5/olivier.png The Team https://images.squarespace-cdn.com/content/v1/5fdc70dff65a9a5fd491b52a/a34a35fa-9bc2-40e5-abe8-e04b5defc9c6/elodie.jpg The Team https://images.squarespace-cdn.com/content/v1/5fdc70dff65a9a5fd491b52a/5841ed08-96ce-4094-b215-597288ab6c25/bowhead_square.jpg The Team https://images.squarespace-cdn.com/content/v1/5fdc70dff65a9a5fd491b52a/8913cf59-80e9-4b3b-a1b8-121ed1bf55e1/florence.png The Team https://images.squarespace-cdn.com/content/v1/5fdc70dff65a9a5fd491b52a/b32de3de-c5c0-4f50-992a-cb3654746847/alysann.png The Team https://images.squarespace-cdn.com/content/v1/5fdc70dff65a9a5fd491b52a/02978d25-24fc-43b1-b44d-f6fce1351502/hannah.jpg The Team https://images.squarespace-cdn.com/content/v1/5fdc70dff65a9a5fd491b52a/99e5a8e4-36f0-4dac-bb2b-9a5b4bfca498/Anthony.jpg The Team https://images.squarespace-cdn.com/content/v1/5fdc70dff65a9a5fd491b52a/b27b38fb-3ea5-4f3f-85b3-ba82836fa1d5/sara.png The Team https://images.squarespace-cdn.com/content/v1/5fdc70dff65a9a5fd491b52a/9ea6fea2-d385-4641-bcf1-7a49bff68cf7/david.png The Team https://gamma-research.space/contact daily 0.75 2022-08-04 https://images.squarespace-cdn.com/content/v1/5fdc70dff65a9a5fd491b52a/1625857040752-RXBWPE87SJAN1WEWUV0I/Screen+Shot+2021-07-09+at+2.55.49+PM.png Contact - Contact us! jruan@ubishops.ca (514) 463-5414 Mailing Address: 2600 Rue College Sherbrooke, Québec J1M 1Z7 Canada Campus Office: Johnson 104C https://gamma-research.space/about-me daily 0.75 2026-03-26 https://images.squarespace-cdn.com/content/v1/5fdc70dff65a9a5fd491b52a/21739366-9579-4c69-b193-d0e5fd8d2d59/photo_JohnRuan.png
