The accretion properties of a low-mass Active Galactic Nucleus: UGC 6728
Prantik Nandi, Sachindra Naik, Arka Chatterjee +3
We present a comprehensive analysis of approximately years () of X-ray observations of UGC~6728, a low-mass bare AGN, for the first time. Our study encompasses both…
Coronal Properties of Low-Accreting AGNs using Swift, XMM-Newton and NuSTAR Observations
Arghajit Jana, Arka Chatterjee, Hsiang-Kuang Chang +6
We studied the broadband X-ray spectra of {\it Swift}/BAT selected low-accreting AGNs using the observations from {\it XMM-Newton}, {\it Swift}, and {\it NuSTAR} in the energy rang…
Gas, dust, and the CO-to-molecular gas conversion factor in low-metallicity starbursts
L. K. Hunt, F. Belfiore, F. Lelli +19
The factor relating CO emission to molecular hydrogen column density, XCO, is still subject to uncertainty, in particular at low metallicity. Here, to quantify XCO at two different…
The ultra-dense, interacting environment of a dual AGN at z 3.3 revealed by JWST/NIRSpec IFS
M. Perna, S. Arribas, M. Marshall +18
LBQS 0302-0019 is a blue quasar (QSO) at z ~ 3.3, hosting powerful outflows, and residing in a complex environment consisting of an obscured AGN candidate, and multiple companions,…
Investigation of a small X-ray flaring event in NLS1 galaxy NGC 4051
Neeraj Kumari, Arghajit Jana, Sachindra Naik +1
We performed a detailed broadband spectral and timing analysis of a small flaring event of ~120 ks in a narrow-line Seyfert 1 galaxy NGC 4051 using simultaneous XMM-Newton and NuST…
In-orbit Performance of the Near-Infrared Spectrograph NIRSpec on the James Webb Space Telescope
T. Böker, T. L. Beck, S. M. Birkmann +47
The Near-Infrared Spectrograph (NIRSpec) is one of the four focal plane instruments on the James Webb Space Telescope. In this paper, we summarize the in-orbit performance of NIRSp…
