Star formation in young star cluster NGC 1893
Saurabh Sharma, A. K. Pandey, D. K. Ojha +6
We present a comprehensive multi-wavelength study of the star-forming region NGC 1893 to explore the effects of massive stars on low-mass star formation. Using near-infrared colour…
The 2019 International Women's Day event: A two-step solar flare with multiple eruptive signatures and low Earth impact
Dumbovic, M., Veronig +15
We present a detailed analysis of an eruptive event that occurred on early 2019 March 8 in active region AR 12734, to which we refer as the International Women's day event. The eve…
The potential of asteroseismology for probing the core chemical stratification in white dwarf stars
N. Giammichele, S. Charpinet, P. Brassard +2
Context. The details of the C/O core structure in white dwarf stars has mostly remained inaccessible to the technique of asteroseismology, despite several attempts carried out in t…
Optical Spectroscopic Observations of Gamma-Ray Blazar Candidates. VII. Follow-up Campaign in the Southern Hemisphere
Peña-Herazo, H. A., Marchesini +29
Searching for low energy counterparts of gamma-ray sources is one of the major challenges in modern gamma-ray astronomy. In the third Fermi source catalog about 30 % of detected so…
Cluster Hot Flow Anomaly Observations During Solar Cycle Minimum
Gabor Facsko, Mariella Tatrallyay, Geza Erdos +2
Hot flow anomalies (HFAs) are studied using observations of the FGM magnetometer and the CIS plasma detector aboard the four Cluster spacecraft. Previously we studied several speci…
Cooperative emission in quantum plasmonic superradiance
H. Varguet, S. Guérin, H. R. Jauslin +1
Plasmonic superradiance originates from the plasmon mediated strong correlation that builds up between dipolar emitters coupled to a metal nanoparticle. This leads to a fast burst…
Optical spectroscopic observations of gamma-ray blazar candidates VIII: the 2016-2017 follow up campaign carried out at SPM, NOT, KPNO and SOAR telescopes
Marchesini, E. J., Peña-Herazo +24
The third Fermi source catalog lists 3033 gamma-ray sources above significance. More than 30% are classified as either unidentified/unassociated Gamma-ray sources (UGSs), wit…
NGC 4262: a Virgo galaxy with an extended ultraviolet ring
Bettoni, D., Buson +3
The Galaxy Ultraviolet Explorer (GALEX) satellite has recently shown the presence of an extended, outer ring studded with UV-bright knots surrounding the lenticular galaxy NGC 4262…
Half-lives of neutron-rich Cd
Dunlop, R., Bildstein +69
The -decay half-lives of Cd have been measured with the newly commissioned GRIFFIN -ray spectrometer at the TRIUMF-ISAC facility. The time structures of…
Solving the inverse problem for an ordinary differential equation using conjugation
Alfaro Vigo, D. G, Alvarez +6
We consider the following inverse problem for an ordinary differential equation (ODE): given a set of data points , find an ODE $x^\prime(t) = v (x)…
Beyond the disk: EUV coronagraphic observations of the Extreme Ultraviolet Imager on board Solar Orbiter
Auchère, F., Berghmans +58
Most observations of the solar corona beyond 2 Rs consist of broadband visible light imagery from coronagraphs. The associated diagnostics mainly consist of kinematics and derivati…
Fundamental parameters for 45 open clusters with Gaia DR2, an improved extinction correction and a metallicity gradient prior
H. Monteiro, W. S. Dias, A. Moitinho +5
Reliable fundamental parameters of open clusters such as distance, age and extinction are key to our understanding of Galactic structure and stellar evolution. In this work we use…
UWISH2 -- The UKIRT Widefield Infrared Survey for H2
D., Froebrich, C. J. +56
We present the goals and preliminary results of an unbiased, near-infrared, narrow-band imaging survey of the First Galactic Quadrant (10deg<l<65deg ; -1.3deg<b<+1.3deg). This area…
Properties of neutron star crust with improved nuclear physics: Impact of chiral EFT interactions and experimental nuclear masses
Grams, G., Margueron +5
A compressible liquid-drop approach adjusted to uniform matter many-body calculations based on chiral EFT interactions and to the experimental nuclear masses is used to investigate…
HD97048: a closer look to the disk
Doucet, C., Habart +11
Aims: Today, large ground-based instruments, like VISIR on the VLT, providing diffraction-limited (about 0.3 arcsec) images in the mid-infrared where strong PAH features appear ena…
Performance improvement of refractometric sensors through hybrid plasmonic-Fano resonances
Elshorbagy, M., Cuadrado +6
In this paper, we present a plasmonic refractometric sensor that works under normal incidence; allowing its integration on a fiber tip. The sensor's material and geometry exploit t…
