Search for low mass vector resonances decaying into quark-antiquark pairs in proton-proton collisions at s=13 TeV [PDF]
Physical Review D, 2019 A search for low mass narrow vector resonances decaying into quark-antiquark pairs is presented. The analysis is based on data collected in 2017 with the CMS detector at the LHC in proton-proton collisions at a center-of-mass energy of 13 TeV ...

The Compositional Diversity of Low-Mass Exoplanets [PDF]
Annual Review of Earth and Planetary Science, 2019 Low-mass planets have an extraordinarily diverse range of bulk compositions, from primarily rocky worlds to those with deep gaseous atmospheres. As techniques for measuring the masses of exoplanets advance the field toward the regime of rocky planets ...

Low-Mass Dark Matter Search with the DarkSide-50 Experiment. [PDF]
Physical Review Letters, 2018 We present the results of a search for dark matter weakly interacting massive particles (WIMPs) in the mass range below 20 GeV/c^{2} using a target of low-radioactivity argon with a 6786.0 kg d exposure.

Identifying AGNs in Low-mass Galaxies via Long-term Optical Variability [PDF]
Astrophysical Journal, 2018 We present an analysis of the nuclear variability of ∼28,000 nearby (z < 0.15) galaxies with Sloan Digital Sky Survey (SDSS) spectroscopy in Stripe 82.

A noninteracting low-mass black hole–giant star binary system [PDF]
Science, 2018 A black hole hiding in a binary star As material falls toward a black hole, it heats up and emits x-rays. Almost all black holes are discovered by this x-ray emission. Thompson et al.

Compositional Imprints in Density–Distance–Time: A Rocky Composition for Close-in Low-mass Exoplanets from the Location of the Valley of Evaporation [PDF]
, 2017 We use an end-to-end model of planet formation, thermodynamic evolution, and atmospheric escape to investigate how the statistical imprints of evaporation depend on the bulk composition of planetary cores (rocky versus icy).

Galactic Winds in Low-mass Galaxies [PDF]
Proceedings of the International Astronomical Union, 2018 Stellar-feedback-driven outflows are predicted to play a fundamental role in the baryon cycle of low-mass galaxies. However, observational constraints of winds in nearby dwarf galaxies are limited, as outflows are transient, intrinsically low surface ...

Low-mass nitrogen-, oxygen-bearing, and aromatic compounds in Enceladean ice grains
Monthly notices of the Royal Astronomical Society, 2019 Saturn’s moon Enceladus is erupting a plume of gas and ice grains from its south pole. Linked directly to the moon’s subsurface global ocean, plume material travels through cracks in the icy crust and is ejected into space.

Electron-capture and Low-mass Iron-core-collapse Supernovae: New Neutrino-radiation-hydrodynamics Simulations [PDF]
, 2017 We present new 1D (spherical) and 2D (axisymmetric) simulations of electron-capture (EC) and low-mass iron-core-collapse supernovae (SN). We consider six progenitor models: the ECSN progenitor from Nomoto; two ECSN-like low-mass low-metallicity iron-core

SDSS-IV MaNGA: evidence of the importance of AGN feedback in low-mass galaxies [PDF]
, 2017 We present new evidence for AGN feedback in a subset of 69 quenched low-mass galaxies ($M_{\star} \lesssim 5\times10^{9}$ M$_{\odot}$, $M_{\rm{r}} > -19$) selected from the first two years of the SDSS-IV MaNGA survey.
