Accretion rates ( $\dot{M}$ ) of young stars show a strong correlation with object mass ( M ); however, extension of the $\dot{M}\mbox{--}M$ relation into the substellar regime is less certain. Here, we present the Comprehensive Archive of Substellar

Near-infrared Accretion Signatures from the Circumbinary Planetary Mass Companion Delorme 1 (AB)b
Autor: S. K. Betti, K. B. Follette, K. Ward-Duong, Y. Aoyama, G.-D. Marleau, J. Bary, C. Robinson, M. Janson, W. Balmer, G. Chauvin, P. Palma-Bifani
Accretion signatures from bound brown dwarf and protoplanetary companions provide evidence for ongoing planet formation, and accreting substellar objects have enabled new avenues to study the astrophysical mechanisms controlling formation and accreti

This work gives an update to existing reconstructions of the Galactic Faraday rotation sky by processing almost all Faraday rotation data sets available at the end of the year 2020. Observations of extra-Galactic sources in recent years have, among o

A broad-band spectro-polarimetric view of the NVSS rotation measure catalogue – I. Breaking the nπ-ambiguity
Autor: Yik Ki Ma, Aritra Basu, S. A. Mao, S. K. Betti, Jeroen Stil, Jennifer West, Carl Heiles, Alex S. Hill
Publikováno v: Monthly Notices of the Royal Astronomical Society. 487:3432-3453
The NRAO VLA Sky Survey (NVSS) Rotation Measure (RM) catalogue is invaluable for the study of cosmic magnetism. However, the RM values reported in it can be affected by n$\pi$-ambiguity, resulting in deviations of the reported RM from the true values

Robustness of Synthetic Observations in Producing Observed Core Properties: Predictions for the TolTEC Clouds to Cores Legacy Survey
Autor: S. K. Betti, R. Gutermuth, S. Offner, G. Wilson, A. Sokol, R. Pokhrel
We use hydrodynamical simulations of star-forming gas with stellar feedback and sink particles (proxies for young stellar objects, i.e., YSOs) to produce and analyze synthetic 1.1mm continuum observations at different distances (150 - 1000pc) and age

A broad-band spectro-polarimetric view of the NVSS rotation measure catalogue – II. Effects of off-axis instrumental polarization
Autor: S. A. Mao, Aritra Basu, Yik Ki Ma, Alex S. Hill, Carl Heiles, Jennifer West, S. K. Betti, Jeroen Stil
The NRAO VLA Sky Survey (NVSS) Rotation Measure (RM) catalogue has enabled numerous studies in cosmic magnetism, and will continue being a unique dataset complementing future polarisation surveys. Robust comparisons with these new surveys will howeve

The Astrophysical Journal, American Astronomical Society, 2019, 874 (1), pp.53. ⟨10.3847/1538-4357/ab07b3⟩
We present new ALMA dust continuum observations of 101 $\log(\mathrm{M}_* / \mathrm{M}_\odot)$ > 9.5 galaxies in the COSMOS field to study the effect of environment on the interstellar medium at z ~ 0.7. At this redshift, our targets span a wide rang

Constraining the Magnetic Field of the Smith High-velocity Cloud Using Faraday Rotation
Autor: S. A. Mao, Bryan Gaensler, Alex S. Hill, Robert A. Benjamin, Felix J. Lockman, S. K. Betti, Naomi McClure-Griffiths
Publikováno v: The Astrophysical Journal. 871:215
The Smith Cloud is a high velocity cloud (HVC) with an orbit suggesting it has made at least one passage through the Milky Way disk. A magnetic field found around this cloud has been thought to provide extra stability as it passes through the Galacti
