Extrapolating heterogeneous time-series gene expression data using Sagittarius

Nature Machine Intelligence, 2023
Understanding the temporal dynamics of gene expression is crucial for developmental biology, tumor biology, and biogerontology. However, some timepoints remain challenging to measure in the lab, particularly during very early or very late stages of a ...

Gamma-ray emission from the Sagittarius dwarf spheroidal galaxy due to millisecond pulsars [PDF]

Nature Astronomy, 2022
The Fermi bubbles are giant, γ-ray-emitting lobes emanating from the nucleus of the Milky Way discovered in ~1–100 GeV data collected by the Large Area Telescope on board the Fermi Gamma-Ray Space Telescope. Previous work has revealed substructure within

SELECTING SAGITTARIUS: IDENTIFICATION AND CHEMICAL CHARACTERIZATION OF THE SAGITTARIUS STREAM [PDF]

Astrophysical Journal, 2015
Wrapping around the Milky Way, the Sagittarius stream is the dominant substructure in the halo. Our statistical selection method has allowed us to identify 106 highly likely members of the Sagittarius stream. Spectroscopic analysis of metallicity and kinematics of all members provides us with a new mapping of the Sagittarius stream.

Constraints on horizonless objects after the EHT observation of Sagittarius A*

Journal of Cosmology and Astroparticle Physics, 2022
The images of Sagittarius A* recently released by the Event Horizon Telescope collaboration have been accompanied [ Astrophys. J. Lett. 930 (2022) L17] by an analysis of the constraints on the possible absence of a trapping horizon, i.e.

A Diffuse Metal-poor Component of the Sagittarius Stream Revealed by the H3 Survey [PDF]

Astrophysical Journal, 2020
The tidal disruption of the Sagittarius dwarf galaxy has generated a spectacular stream of stars wrapping around the entire Galaxy. We use data from Gaia and the H3 Stellar Spectroscopic Survey to identify high-quality Sagittarius members based on their ...

Neutrino lighthouse at Sagittarius A* [PDF]

Physical Review D, 2014
We investigate whether a subset of high-energy events observed by IceCube may be due to neutrinos from Sagittarius A*. We check both spatial and temporal coincidences of IceCube events with other transient activities of Sagittarius A*. Among the seven IceCube shower events nearest to the galactic center, we have found that event 25 has a time very ...
