Abstract We study the physical properties and 3D distribution of molecular clouds (MCs) toward Cygnus region using MWISP CO survey Gaia DR3 data. Based on Gaussian decomposition clustering for 13 lines, over 70% fluxes are recovered. With identification result structures, two models designed to measure distances gas in velocity crowding regions. The more than 200 large structures obtained 150 deg 2 region. Additionally, tens identified MC coincide well with masers and/or intense mid-IR...
We study the gas inflows towards Galactic Central Molecular Zone (CMZ) based on morphological and kinematic features from MWISP in region of l=1.2 deg--19.0 deg |b|<3.0 deg. find that near dust lane extends to l~15 deg, which end large-scale structure intersects with 3 kpc-ring at a distance ~5 kpc. Intriguingly, many filamentary MCs, together bow-like/ballistic-like clouds continuous CO notable velocity gradient, are finely outlined along long structure. These MCs also have relatively large...
Abstract We present a new large-scale (2° × 2°) simultaneous 12 CO, 13 and C 18 O ( J = 1–0) mapping of L1188 with the Purple Mountain Observatory 13.7 m telescope. Our observations have revealed that consists two nearly orthogonal filamentary molecular clouds at clearly separated velocities. Toward intersection showing large velocity spreads, we find several bridging features connecting in velocity, an open arc structure exhibits high excitation temperatures, enhanced CO emission, broad...

Modern (sub)millimeter interferometers, such as ALMA and NOEMA, offer high angular resolution unprecedented sensitivity. This provides the possibility to characterize morphology of gas dust in distant galaxies. To assess capabilities current software recovering morphologies surface brightness profiles interferometric observations, we tested performance Spergel model for fitting uυ -plane, which has been recently implemented IRAM GILDAS ( uv_fit ). provide an alternative Sérsic profile, with...
We present a systematic analysis of the velocity structure functions (VSFs) 167 molecular clouds with angular sizes greater than $\sim$176 arcmin$^2$ in three sectors Galactic mid-plane. calculated 1st- to 3rd-order VSFs and found that 60\% exhibit power-law distributions. The relative exponents are consistent predictions from intermittent turbulence models. Column density weighting reduces proportion steepens VSF slopes, implying reduction turbulent energy high-density regions. All show...
Abstract We uncovered a more tilted molecular gas structure with highly negative velocities located near the dust lane. Our observations show that approaching flows from overshoot process are captured by gravitational potential of bar and then flow toward Galactic central zone (CMZ) through channel.

Bronchiolar adenoma (BA) is a benign lung tumor characterized by nodular proliferation of bilayered bronchiolar-type epithelium with continuous basal cell layer. The genetic characteristics BA are not well understood. However, mutations commonly associated adenocarcinoma, such as BRAF V600E, epidermal growth factor receptor (EGFR) mutations, and ALK rearrangements, have recently been identified in this context. This report describes case 43-year-old male who presented mixed ground-glass...

To investigate whether distinctions exist between low- and high-luminosity Class ii 6.7 GHz methanol masers, we have undertaken multi-line mapping observations of various molecular lines, including the NH3 (1,1), (2,2), (3,3), (4,4), 12CO (1–0) transitions, toward a sample nine low-luminosity masers eight for which already had spectral line data. Emission in (3,3) transitions was detected out maser sources, 14 cores were identified. We derive densities, column temperatures, core sizes,...
Abstract With new high-resolution CO and H i data, we revisited the large-scale interstellar medium (ISM) environment toward SS 433/W50 system. We find that two interesting molecular cloud (MC) concentrations, G39.315−1.155 G40.331−4.302, are well aligned along precession cone of 433 within a smaller opening angle ∼±7°. The kinematic features MCs at ∼73–84 km s −1 , as those corresponding atomic-gas counterparts, consistent with characteristics 433. That is, receding gas from jet is probably...
