Trigonometric parallaxes of star forming regions in the Sagittarius spiral arm

open access: yes, 2014
We report measurements of parallaxes and proper motions of ten high-mass star-forming regions in the Sagittarius spiral arm of the Milky Way as part of the BeSSeL Survey with the VLBA.

Stellar streams as gravitational experiments I. The case of Sagittarius [PDF]

open access: yes, 2017
Tidal streams of disrupting dwarf galaxies orbiting around their host galaxy offer a unique way to constrain the shape of galactic gravitational potentials. Such streams can be used as leaning tower gravitational experiments on galactic scales.

High-resolution Spectroscopy of the GD-1 Stellar Stream Localizes the Perturber near the Orbital Plane of Sagittarius [PDF]

open access: yesAstrophysical Journal, 2020
The 100° long thin stellar stream in the Milky Way halo, GD-1, has an ensemble of features that may be due to dynamical interactions. Using high-resolution MMT/Hectochelle spectroscopy we show that a spur of GD-1-like stars outside of the main stream are

Testing alternative theories of gravity by fitting the hot-spot data of Sgr A*

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
We are fitting dynamics of electrically neutral hot-spot orbiting around Sagittarius A* (Sgr A*) source in Galactic center, represented by various modifications of the standard Kerr black hole (BH), to the three flares observed by the GRAVITY instrument ...

The subcellular distribution of phosphorylated Y‐box‐binding protein‐1 at S102 in colorectal cancer patients, stratified by KRAS mutational status and clinicopathological features

open access: yesMolecular Oncology, EarlyView.
This study identifies nuclear YB‐1 S102 phosphorylation as a marker associated with KRAS and FBXW7 mutations in colorectal cancer. Mutated KRAS correlates specifically with nuclear, not cytoplasmic, S102 YB‐1. These findings provide the first ex vivo evidence of this link in CRC and suggest future studies should assess the prognostic and therapeutic ...

GALACTIC CENTER MINISPIRAL: INTERACTION MODES OF NEUTRON STARS

open access: yesActa Polytechnica, 2015
Streams of gas and dust in the inner parsec of the Galactic center form a distinct feature known as the Minispiral, which has been studied in radio waveband as well as in the infrared wavebands.

General relativistic MHD simulations of non-thermal flaring in Sagittarius A* [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2020
Sgr A* exhibits regular variability in its multiwavelength emission, including daily X-ray flares and roughly continuous near-infrared (NIR) flickering.

Activation and Stabilization Strategies of Aluminum Metal Anode Toward High Performance Aqueous Al Metal Batteries

open access: yesAdvanced Materials, EarlyView.
This review spotlights the critical challenges faced by aluminum metal anodes and aqueous electrolytes. Recent progress on activating and stabilizing Al metal anode is summarized and discussed in terms of two aspects, including anode engineering and electrolyte optimization. Finally, some revelatory insights and possible strategies are provided for the
