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…

Gaia24ccy: An outburst followed the footsteps of its predecessor

Koshvendra Singh, Joe P. Ninan, Zhen Guo +25

Accretion-driven outbursts in young stellar objects remain poorly understood, largely limited by a statistically small sample of closely followed-up events. This underscores the im…

A Submillimeter Perspective on the GOODS Fields (SUPER GOODS) - II. The High Radio Power Population in the GOODS-N

Amy J. Barger, Lennox L. Cowie, Frazer N. Owen +2

We use ultradeep 20 cm data from the Karl G. Jansky Very Large Array and 850 micron data from SCUBA-2 and the Submillimeter Array of an 124 arcmin^2 region of the Chandra Deep Fiel…

The MicroJansky Radio Galaxy Population

A. J. Barger, L. L. Cowie, W. -H. Wang

We use highly spectroscopically complete observations of the radio sources from the VLA 1.4 GHz survey of the HDF-N region to study the faint radio galaxy population and its evolut…

The Cosmic Evolution of Hard X-ray Selected Active Galactic Nuclei

A. J. Barger, L. L. Cowie, R. F. Mushotzky +4

We use highly spectroscopically complete deep and wide-area Chandra surveys to determine the cosmic evolution of hard X-ray-selected AGNs. We determine hard X-ray luminosity functi…
