We present the discovery of three new low-latitude (|b| ~ 20) Milky Way satellites: Yasone-1, Yasone-2, and Yasone-3. They were identified in our search for compact stell…
A Jetted Wandering Massive Black Hole Candidate in a Dwarf Galaxy
Yuanqi Liu, Tao An, Mar Mezcua +4
Wandering massive black holes (MBHs) are thought to form through gravitational recoil or galaxy mergers, but observational confirmation of their displacement in dwarf galaxies, cri…
Beyond Traditional Diagnostics: Identifying Active Galactic Nuclei with Spectral Energy Distribution Fitting in DESI Data
M. Siudek, M. Mezcua, C. Circosta +36
Active galactic nuclei (AGN) are typically identified through their distinctive X-ray or radio emissions, mid-infrared (MIR) colors, or emission lines. However, each method capture…
