Constraining the Binarity of Black Hole Candidates: A Proof-of-concept Study of Gaia BH1 and Gaia BH2 [PDF]

open access: yesAstrophysical Journal, 2023
Nearly a hundred binary black holes (BBHs) have been discovered with gravitational-wave signals emitted at their merging events. Thus, it is quite natural to expect that significantly more abundant BBHs with wider separations remain undetected in the ...

A Triple Scenario for the Formation of Wide Black Hole Binaries Such as Gaia BH1 [PDF]

open access: yesAstrophysical Journal, 2023
Recently, several noninteracting black hole–stellar binaries have been identified in Gaia data—for example, Gaia BH1, where a Sun-like star is in a moderately eccentric (e = 0.44) 185 days orbit around a black hole.

JWST Reveals a Luminous Infrared Source at the Position of the Failed Supernova Candidate N6946-BH1 [PDF]

open access: yesAstrophysical Journal, 2023
N6946-BH1 (BH1) is the first plausible candidate for a failed supernova (SN), a peculiar event in which a massive star disappears without the expected bright SN, accompanied by collapse into a black hole (BH).

Updated radial velocities and new constraints on the nature of the unseen source in NGC1850 BH1 [PDF]

open access: yes, 2023
A black hole candidate orbiting a luminous star in the Large Magellanic Cloud young cluster NGC 1850 ($\sim100$Myr) has recently been reported based on radial velocity and light curve modelling. Subsequently, an alternative explanation has been suggested

NGC 1850 BH1 is another stripped-star binary masquerading as a black hole [PDF]

open access: yes, 2021
We show that the radial velocity-variable star in the black hole candidate NGC 1850 BH1 cannot be a normal ∼ 5M subgiant, as was proposed, but is an overluminous stripped-envelope star with mass ∼ 1M . The result follows directly from the star’s observed

ExoMiner: A Highly Accurate and Explainable Deep Learning Classifier That Validates 301 New Exoplanets [PDF]

open access: yesAstrophysical Journal, 2021
The Kepler and Transiting Exoplanet Survey Satellite (TESS) missions have generated over 100,000 potential transit signals that must be processed in order to create a catalog of planet candidates.

Multichannel Analysis of Surface Waves (MASW) to Estimate the Shear Wave Velocity for Engineering Characterization of Soils at Hawassa Town, Southern Ethiopia

open access: yesInternational Journal of Geophysics, Volume 2022, Issue 1, 2022., 2022
Site characterization is a prerequisite for the successful and economic design of engineering structures and earthworks by providing geological information for any proposed project. Until now, no detail study has been carried out on the site characterization and classification using shear wave velocity (Vs) up to the top 30 m depth in Hawassa town. For

Systems-level regulation of microRNA networks by miR-130/301 promotes pulmonary hypertension

open access: yesJournal of Clinical Investigation, 2022
Development of the vascular disease pulmonary hypertension (PH) involves disparate molecular pathways that span multiple cell types. MicroRNAs (miRNAs) may coordinately regulate PH progression, but the integrative functions of miRNAs in this process have

Nasal residence time and rheological properties of a new bentonite-based thixotropic gel emulsion nasal spray – AM-301

open access: yesDrug Development and Industrial Pharmacy, 2023
Objective The present work provides characterization of rheological properties of a new bentonite-based thixotropic gel emulsion nasal spray (AM-301), its nasal residence time, distribution, safety and tolerability. Significance The nasal epithelium is a
