Searching for intermediate-mass black holes in NGC3310
Megan Argo, Joseph Coppola, Mar Mezcua +2
Intermediate-mass black holes are theoretically predicted but observationally elusive, and evidence for them is often indirect. The nearby face-on spiral galaxy NGC3310 has hosted…
Titans of the Early Universe: The Prato Statement on the Origin of the First Supermassive Black Holes
Tyrone E. Woods, Bhaskar Agarwal, Volker Bromm +30
In recent years, the discovery of massive quasars at z~7 has provided a striking challenge to our understanding of the origin and growth of supermassive black holes in the early Un…
Intra-night optical variability of AGN in the COSMOS field with the KMTNet
Joonho Kim, Marios Karouzos, Myungshin Im +5
Active Galactic Nucleus (AGN) variability can be used to study the physics of the region in the vicinity of the central black hole. In this paper, we investigated intra-night optic…
Glimmering in the dark: modeling the low-mass end of the relation and of the quasar luminosity function
Fabio Pacucci, Abraham Loeb, Mar Mezcua +1
The relation establishes a connection between central black holes (BHs) and their host spheroids. Supported by observations at $M_{\bullet} \gtrsim 10^5 \, M_{\od…
The extended radio jet of an off-nuclear low-mass AGN in NGC 5252
M. Mezcua, M. Kim, L. C. Ho +1
CXO J133815.6+043255 is an ultraluminous X-ray source (ULX) with ultraviolet, optical, and radio counterparts located 10 kpc away from the nucleus of the galaxy NGC 5252. Optical s…
Exploring the limits of AGN feedback: black holes and the star formation histories of low-mass galaxies
Ignacio Martin-Navarro, Mar Mezcua
Energy feedback, either from active galactic nuclei (AGN) or from supernovae, is required to understand galaxy formation within a -Cold Dark Matter cosmology. We study a sample…
