TESS Discovery of Twin Planets near 2:1 Resonance around Early M-Dwarf TOI 4342
Evan Tey, Chelsea X. Huang, Michelle Kunimoto +28
With data from the Transiting Exoplanet Survey Satellite (TESS), we showcase improvements to the MIT Quick-Look Pipeline (QLP) through the discovery and validation of a multi-plane…
A search for variable subdwarf B stars in TESS Full Frame Images III. An update on variable targets in both ecliptic hemispheres -- contamination analysis and new sdB pulsators
S. K. Sahoo, A. S. Baran, H. L. Worters +2
We present an update on the variable star survey performed on the TESS 30 min Full Frame Image (FFI) data reported by our first two papers in this series. This update includes a co…
Trajectory Based RFI Subtraction and Calibration for Radio Interferometry
Chris Finlay, Bruce A. Bassett, Martin Kunz +1
Radio interferometry calibration and Radio Frequency Interference (RFI) removal are usually done separately. Here we show that jointly modelling the antenna gains and RFI has signi…
Optical and mid-infrared line emission in nearby Seyfert galaxies
A. Feltre, C. Gruppioni, L. Marchetti +24
Line ratio diagnostics provide valuable clues on the source of ionizing radiation in galaxies with intense black hole accretion and starbursting events, such as local Seyfert or ga…
Multi-wavelength study of TeV blazar 1ES 1218+304 using gamma-ray, X-ray and optical observations
Rishank Diwan, Raj Prince, Aditi Agarwal +6
We report the multi-wavelength study for a high-synchrotron-peaked BL Lac 1ES 1218+304 using near-simultaneous data obtained during the period from January 1, 2018, to May 31, 2021…
The outburst of the changing-look AGN IRAS23226-3843 in 2019
Wolfram Kollatschny, Dirk Grupe, Michael L. Parker +8
IRAS23226-3843 has previously been classified as a changing-look AGN based on X-ray and optical spectral variations. In 2019, Swift observations revealed a strong rebrightening in…
