The Success of Optical Variability in Uncovering AGNs in Low-stellar Mass Galaxies
S. Bernal, P. Sánchez-Sáez, P. Arévalo +3
We used random forest algorithms to classify all objects in a large portion of the sky, using optical light curves obtained, or built from images provided, by the Zwicky Transient…
Oxygen Isotope Ratios in Hydrogen-Deficient Carbon Stars: A Correlation with Effective Temperature and Implications for White Dwarf Merger Outcomes
Advait Mehla, Mansi M. Kasliwal, Viraj Karambelkar +5
Hydrogen-deficient Carbon (HdC) stars are a class of supergiants with anomalous chemical compositions, suggesting that they are remnants of CO-He white dwarf (WD) mergers. This cla…
Investigating late-stage particle production in pp collisions with Balance Functions
Alexandru Manea, Claude Pruneau, Diana Catalina Brandibur +4
Balance functions have been regarded in the past as a method of investigating the late-stage hadronization found in the presence of a strongly-coupled medium. They are also used to…
Investigating Changing-Look Active Galactic Nuclei with Long-term Optical and X-Ray Observations
A. Jana, C. Ricci, M. J. Temple +7
Changing-look active galactic nuclei (CLAGNs) show the appearance and disappearance of broad emission lines in their UV/optical spectra on timescales of months to decades. Here, we…
A tell-tale tracer for externally irradiated protoplanetary disks: comparing the [CI] 8727 A line and ALMA observations in proplyds
Mari-Liis Aru, Karina Mauco, Carlo F. Manara +15
The evolution of protoplanetary disks in regions with massive OB stars is influenced by externally driven winds that deplete the outer parts of disks. These winds have previously b…
Supernova Shocks in Molecular Clouds: Shocks Driven into Dense Cores in IC 443 and 3C 391
William T. Reach, Ngoc Le Tram, Curtis DeWitt +3
Supernova shocks into dense molecular cores in IC 443 (clumps B, C, and G) and 3C 391 were observed using the Stratospheric Observatory for Infrared Astronomy and complemented by a…
Running Hubble constant: evolutionary Dark Energy
Giovanni Montani, Nakia Carlevaro, Maria G. Dainotti
We discuss an evolutionary dark energy model, based on the presence of non-equilibrium effects on the dark energy constituents, which are described via a bulk viscosity contributio…
First Use of GPS Satellites for Beam Calibration of Radio Dish Telescopes
Sabrina Berger, Arianna Lasinski, Vincent MacKay +4
We present results from the first application of the Global Navigation Satellite System (GNSS; e.g., the Global Positioning System, GPS) for radio beam calibration using a commerci…
Model-independent calibration of Gamma-Ray Bursts with neural networks
Purba Mukherjee, Maria Giovanna Dainotti, Konstantinos F. Dialektopoulos +2
The Cold Dark Matter (CDM) cosmological model has been highly successful in predicting cosmic structure and evolution, yet recent precision measurements have highlighted dis…
Gravitational-Wave Parameter Estimation in non-Gaussian noise using Score-Based Likelihood Characterization
Ronan Legin, Maximiliano Isi, Kaze W. K. Wong +2
Gravitational-wave (GW) parameter estimation typically assumes that instrumental noise is Gaussian and stationary. Obvious departures from this idealization are typically handled o…
The Density and Ionization Profile of Optically Dark and High Redshift GRBs Probed by X-ray Absorption
Eka Puspita Arumaningtyas, Hasan Al Rasyid, Maria Giovanna Dainotti +1
The X-ray column density (NHX) of gamma-ray bursts (GRBs) can probe the local environment of their progenitors over a wide redshift range. Previous work has suggested an increasing…
The NuSTAR Local AGN Distribution Survey (NuLANDS) I: Towards a Truly Representative Column Density Distribution in the Local Universe
Peter G. Boorman, Poshak Gandhi, Johannes Buchner +33
Hard X-ray-selected samples of Active Galactic Nuclei (AGN) provide one of the cleanest views of supermassive black hole accretion, but are biased against objects obscured by Compt…
SOFIA/EXES observations of warm H2 at high spectral resolution: II. IC443C, NGC2071, and 3C391
David A. Neufeld, Curtis DeWitt, Pierre Lesaffre +4
Using the EXES instrument on SOFIA, we have obtained velocity-resolved spectra of several pure rotational lines of H2 toward shocked molecular gas within three Galactic sources: th…
A probe of the maximum energetics of fast radio bursts through a prolific repeating source
O. S. Ould-Boukattine, P. Chawla, J. W. T. Hessels +12
Fast radio bursts (FRBs) are sufficiently energetic to be detectable from luminosity distances up to at least seven billion parsecs (redshift ). Probing the maximum energies…
RHINO: A large horn antenna for detecting the 21cm global signal
Philip Bull, Ahmed El-Makadema, Hugh Garsden +11
The sky-averaged brightness temperature of the 21cm line from neutral hydrogen provides a sensitive probe of the thermal state of the intergalactic medium, particularly before and…
Parameter constraints for accreting millisecond pulsars with synthetic NICER data
Bas Dorsman, Tuomo Salmi, Anna L. Watts +10
Pulse profile modelling (PPM) is a technique for inferring mass, radius and hotspot properties of millisecond pulsars. PPM is now regularly used for analysis of rotation-powered mi…
Bayesian evidence for flux scale errors in Galactic synchrotron maps
Michael J. Wilensky, Melis O. Irfan, Philip Bull
The 408 MHz Haslam map is widely used as a low-frequency anchor for the intensity and morphology of Galactic synchrotron emission. Multi-frequency, multi-experiment fits show evide…
Bright-rimmed clouds in IC 1396 I. Dynamics
Yoko Okada, Slawa Kabanovic, Rolf Güsten +14
We investigate the dynamical and physical structures of bright-rimmed clouds (BRCs) in a nearby HII region. We focused on carbon- and oxygen-bearing species that trace photon-domin…
A Nançay Radio Telescope study of the hyperactive repeating FRB 20220912A
David C. Konijn, Danté M. Hewitt, Jason W. T. Hessels +8
The repeating fast radio burst source FRB 20220912A was remarkably active in the weeks after its discovery. Here we report 696 bursts detected with the Nançay Radio Telescope (NRT)…
Seasonal variation of Saturn's Lyman- brightness
P. Stephenson, T. T. Koskinen, Z. Brown +5
We examine Saturn's non-auroral (dayglow) emissions at Lyman- observed by the {Cassini/UVIS} instrument from 2004 until 2016, to constrain meridional and seasonal trends in the…
