Revealing AGN, young and old stellar populations in HzRGs with PEGASE.3 by Drouart, G., De Breuck, C., Vernet, J., Volmerange, B., Seymour, Nick

“…Making use of the evolutionary code PEGASE.3 and an AGN torus model, we are able to estimate parameters from the AGN torus, the evolved stellar population and the starburst (SB). They reveal that radio galaxies are massive, evolved, forming the bulk of their mass at very high redshift in a short timescale, but experience episodic, strong SB events, often associated with an AGN activity.…”

Combined analysis of Hubble and VLT photometry of the intermediate mass black hole ESO 243-49 HLX-1 by Soria, Roberto

“…Previous separate analyses of these data found that they were consistent with an irradiated accretion disc with contribution from either a very young or very old stellar population, and also indicated that the optical flux of the HLX-1 counterpart could be variable. …”

Chronicling the Host Galaxy Properties of the Remarkable Repeating FRB 20201124A by Fong, W.F., Dong, Y., Leja, J., Bhandari, S., Day, C.K., Deller, A.T., Kumar, P., Prochaska, J.X., Scott, D.R., Bannister, K.W., Eftekhari, T., Gordon, A.C., Heintz, K.E., James, Clancy, Kilpatrick, C.D., Mahony, E.K., Rouco Escorial, A., Ryder, S.D., Shannon, Ryan, Tejos, N.

“…By jointly modeling the 12 filter optical-mid-infrared (MIR) photometry and spectroscopy of the host, we infer a median stellar mass of ∼2 × 1010 M⊙, internal dust extinction AV ≈ 1-1.5 mag, and a mass-weighted stellar population age of ∼5-6 Gyr. Connecting these data to the radio and X-ray observations, we cannot reconcile the broadband behavior with strong active galactic nucleus activity and instead attribute the dominant source of persistent radio emission to star formation, likely originating from the circumnuclear region of the host. …”
