Detection of Deuterated Hydrocarbon Nanoparticles in the Whirlpool Galaxy, M51

The Astrophysical Journal Letters
Deuteration of hydrocarbon material, including polycyclic aromatic hydrocarbons (PAHs), has been proposed to account for the low gas-phase abundances of D in the interstellar medium (ISM). JWST spectra of four star-forming regions in M51 show an emission

Subarcsecond-resolution Imaging of M51 with the International LOFAR Telescope [PDF]

The Astrophysical Journal, 2023
We present an International LOFAR Telescope (ILT) subarcsecond-resolution image of the nearby galaxy M51 with a beam size of 0.″436 × 0.″366 and rms of 46 μ Jy. We compare this image with a European VLBI Network study of M51 and discuss the supernovae in

THE DISTANCE TO M51* [PDF]

The Astrophysical Journal, 2016
ABSTRACT Great investments of observing time have been dedicated to the study of nearby spiral galaxies with diverse goals ranging from understanding the star formation process to characterizing their dark matter distributions. Accurate distances are fundamental to interpreting observations of these galaxies, yet many of the best studied

HI in Arp72 and similarities with M51-type systems [PDF]

The Astronomical Journal, 2011
We present neutral hydrogen (H{\sc i}) observations with the Giant Metrewave Radio Telescope ({\it GMRT}) of the interacting galaxies NGC5996 and NGC5994, which make up the Arp72 system.

Discovery of a 2.8 s Pulsar in a 2 Day Orbit High-mass X-Ray Binary Powering the Ultraluminous X-Ray Source ULX-7 in M51 [PDF]

Astrophysical Journal, 2020
We discovered 2.8 s pulsations in the X-ray emission of the ultraluminous X-ray source (ULX) M51 ULX-7 within the UNSEeN project, which was designed to hunt for new pulsating ULXs (PULXs) with XMM-Newton.

Functional analysis and verification of GYG2 in oncolytic virus-infected glioma [PDF]

BMC Cancer
Background Oncolytic virus has emerged as a promising candidate against tumors by infecting and killing cancer cells. In addition to poor prognosis of patients with glioma, the exact mechanisms driving the oncolytic virus therapy in glioma remain poorly ...

A Phase-resolved View of Millihertz Quasiperiodic Oscillations in the Ultraluminous X-Ray Source M51 ULX-7: Evidence for a Magnetically Truncated Disk and Geometrical Beaming

Astrophysical Journal
X-ray quasiperiodic oscillations (QPOs) are commonly observed in Galactic X-ray binaries and extragalactic ultraluminous X-ray sources (ULXs). In this study, we perform a phase-resolved analysis of recently discovered X-ray mHz QPOs in M51 ULX-7.

Instability analysis for spiral arms of local galaxies: M51, NGC 3627, and NGC 628 [PDF]

, 2021
We investigate dynamical states of grand-design spiral arms in three local galaxies: M51, NGC3627 and NGC628. Based on linear perturbation analysis consideringmultiple components in the galaxies, we compute instability parameters of the spiral arms using
