NGC 7538 : Multiwavelength Study of Stellar Cluster Regions associated with IRS 1-3 and IRS 9 sources
K. K. Mallick, D. K. Ojha, M. Tamura +7
We present deep and high-resolution (FWHM ~ 0.4 arcsec) near-infrared (NIR) imaging observations of the NGC 7538 IRS 1-3 region (in JHK bands), and IRS 9 region (in HK bands) using…
The FAIR Funder pilot programme to make it easy for funders to require and for grantees to produce FAIR Data
P. Wittenburg, H. Pergl Sustkova, A. Montesanti +57
There is a growing acknowledgement in the scientific community of the importance of making experimental data machine findable, accessible, interoperable, and reusable (FAIR). Recog…
Description of turbulent dynamics in the interstellar medium: multifractal/microcanonical analysis I. Application to Herschel observations of the Musca filament
H. Yahia, N. Schneider, S. Bontemps +10
Observations of the interstellar medium (ISM) show a complex density and velocity structure which is in part attributed to turbulence. We here present a self-contained introduction…
Transit timing variations in the WASP-4 planetary system
John Southworth, M. Dominik, U. G. Jorgensen +25
Transits in the planetary system WASP-4 were recently found to occur 80s earlier than expected in observations from the TESS satellite. We present 22 new times of mid-transit that…
Metal-THINGS: The Milky Way twin candidate NGC 3521
L. S. Pilyugin, M. A. Lara-Lopez, G. Tautvaisiene +6
The 3D spectrophotometry measurements of the galaxy NGC~3521, a structural Milky Way analogue (sMWA), were carried out within the Metal-THINGS project. We found that the oxygen abu…
Metal-THINGS: The association and optical characterization of SNRs with HI holes in NGC 6946
M. A. Lara-Lopez, L. S. Pilyugin, J. Zaragoza-Cardiel +9
NGC~6946, also known as the `Fireworks' galaxy, is an unusual galaxy that hosts a total of 225 supernova remnant (SNR) candidates, including 147 optically identified with high [SII…
Multifractal Analysis of the Interstellar Medium. First application to Hi-GAL Observations
D. Elia, F. Strafella, S. Dib +6
The multifractal geometry remains an under-exploited approach to describe and quantify the large-scale structure of interstellar clouds. In this paper, the typical tools of multifr…
Weighing nearby stars with GAIA ?
S. Dib, J. Surdej, J. -F. Claeskens
Microlensing consists in two major effects: (1) variation in the apparent position of the background sources (astrometric component) and (2) flux variations of the background sourc…
H-ATLAS/GAMA: The nature and characteristics of optically red galaxies detected at submillimetre wavelengths
A. Dariush, S. Dib, S. Hony +39
We combine Herschel/SPIRE sub-millimeter (submm) observations with existing multi-wavelength data to investigate the characteristics of low redshift, optically red galaxies detecte…
Gas dynamics in Massive Dense Cores in Cygnus-X
T. Csengeri, S. Bontemps, N. Schneider +2
We study the kinematic properties of dense gas surrounding massive protostars recognized by Bontemps et a. (2010) in a sample of five Massive Dense Cores in Cygnus-X. We investigat…
Gas inflows from cloud to core scales in G332.83-0.55: Hierarchical hub-filament structures and tide-regulated gravitational collapse
J. W. Zhou, S. Dib, M. Juvela +4
The massive star-forming region G332.83-0.55 contains at least two levels of hub-filament structures. The hub-filament structures may form through the "gravitational focusing" proc…
OGLE-2018-BLG-0022: A Nearby M-dwarf Binary
R. A. Street, E. Bachelet, Y. Tsapras +28
We report observations of the binary microlensing event OGLE-2018-BLG-0022, provided by the ROME/REA Survey, which indicate that the lens is a low-mass binary star consisting of M3…
Surface convection and red giants radii measurements
L. Piau, P. Kervella, S. Dib +1
The phenomenological models of convection use characteristic length scales they do not determine but that are chosen to fit solar or stellar observations. We investigate if changes…
Feedback from protoclusters does not significantly change the kinematic properties of the embedded dense gas structures
J. W. Zhou, S. Dib, F. Wyrowski +11
A total of 64 ATOMS sources at different evolutionary stages were selected to investigate the kinematics and dynamics of gas structures under feedback. We identified dense gas stru…
Six Outbursts of Comet 46P/Wirtanen
Michael S. P. Kelley, Tony L. Farnham, Jian-Yang Li +32
Cometary activity is a manifestation of sublimation-driven processes at the surface of nuclei. However, cometary outbursts may arise from other processes that are not necessarily d…
OGLE-2018-BLG-1185b : A Low-Mass Microlensing Planet Orbiting a Low-Mass Dwarf
Iona Kondo, Jennifer C. Yee, David P. Bennett +94
We report the analysis of planetary microlensing event OGLE-2018-BLG-1185, which was observed by a large number of ground-based telescopes and by the Space Telescope. The…
Metal-THINGS: a panchromatic analysis of the local scaling relationships of the dwarf irregular galaxy NGC 1569
