Hot water emission during an outburst in a classical T Tauri star
Zhen Guo, Javier Osses, Vitor Fermiano +34
In this paper, we present observations of an eruptive young star in the Rosette Nebula, identified by the Gaia Science Alerts system using Gaia time series data. We aim to investig…
Synthetic Spectral Library of Optically Thick Atmospheres for Little Red Dots
Hanpu Liu, Yan-Fei Jiang, Eliot Quataert +3
Little Red Dots (LRDs) challenge conventional models of active galactic nuclei. At rest-optical-to-near-infrared (IR) wavelengths, these compact extragalactic objects show blackbod…
"Oh FUors where art thou": A search for long-lasting YSO outbursts hiding in infrared surveys
Carlos Contreras Peña, Jeong-Eun Lee, Ho-Gyu Lee +11
Long-lasting episodes of high accretion can strongly impact stellar and planetary formation. However, the universality of these events during the formation of young stellar objects…
Gravitational Wave Forecasts Constrained by JWST AGN Observations for Early Massive Black Hole Mergers
Hanpu Liu, Kohei Inayoshi
Massive black holes (BHs) grow by gas accretion and mergers, observable through electromagnetic (EM) and gravitational wave (GW) emission. The James Webb Space Telescope (JWST) has…
An outburst and FU Ori-type disk of a former low luminosity protostar
Mizna Ashraf, Jessy Jose, Ho-Gyu Lee +5
Strong accretion outbursts onto protostars are associated with emission dominated by a viscously heated disk, which is characterized by high luminosities. We report the discovery a…
