Chromospherically Active Stars in the MeerKAT Galactic Plane Survey
Okwudili D. Egbo, David A. H. Buckley, Paul J. Groot +4
Stellar magnetic activity has long been established to occur in subsets of late-type main-sequence stars and manifests itself in the form of chromospheric and coronal activity. Thi…
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

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…
Local Volume dwarf KK242: radial velocity, SF region, and metallicity
S. A. Pustilnik, A. L. Tepliakova, Y. A. Perepelitsyna +5
KK242 is a LV dwarf of transition type residing in the void environment. Koda et al. present clear indications on its connection with Scd galaxy NGC6503. This implies the distance…
Transitioning from a bounce to inflation
Richard Daniel, Mariam Campbell, Carsten van de Bruck +1
Non-singular bouncing cosmologies are well--motivated models for the early universe. Recent observational data are consistent with positive spatial curvature and allow for a natura…
Short-period pulsating hot-subdwarf stars observed by TESS I. Southern ecliptic hemisphere
A. S. Baran, V. Van Grootel, R. H. Ostensen +7
We present results of a Transiting Exoplanet Survey Satellite (TESS) search for short-period pulsations in compact stellar objects observed in years 1 and 3 of the TESS mission, du…
Learning to Detect Interesting Anomalies
Alireza Vafaei Sadr, Bruce A. Bassett, Emmanuel Sekyi
Anomaly detection algorithms are typically applied to static, unchanging, data features hand-crafted by the user. But how does a user systematically craft good features for anomali…
Semi-analytic forecasts for Roman -- the beginning of a new era of deep-wide galaxy surveys
L. Y. Aaron Yung, Rachel S. Somerville, Steven L. Finkelstein +11
The Nancy Grace Roman Space Telescope, NASA's next flagship observatory, will redefine deep-field galaxy survey with a field of view two orders of magnitude larger than Hubble and…
Broadband study and the discovery of pulsations from the Be/X-ray binary eRASSU J052914.9-662446 in the Large Magellanic Cloud
C. Maitra, D. Kaltenbrunner, F. Haberl +12
Context. The Magellanic Clouds are our nearest star-forming galaxies. While the population of high-mass X-ray binaries (HMXBs) in the Small Magellanic Cloud (SMC) is relatively wel…
The need for multicomponent dust attenuation in modeling nebular emission: Constraints from SDSS-IV MaNGA
Xihan Ji, Renbin Yan, Kevin Bundy +12
A fundamental assumption adopted in nearly every extragalactic emission-line study is that the attenuation of different emission lines can be described by a single attenuation curv…
Horizon area bound and MOTS stability in locally rotationally symmetric solutions
Abbas M. Sherif, Peter K. S. Dunsby
In this paper, we study the stability of marginally outer trapped surfaces (MOTS), foliating horizons of the form , embedded in locally rotationally symmetric class II perf…
Deciphering the extreme X-ray variability of the nuclear transient eRASSt J045650.3-203750: A likely repeating partial tidal disruption event
Zhu Liu, A. Malyali, M. Krumpe +17
(Abridged) In this paper, we present the results of an exceptional repeating X-ray nuclear transient, eRASSt J045650.3-203750 (hereafter J0456-20), uncovered by SRG/eROSITA in a qu…
