We show herein that the population of star-forming galaxies in the Bremer Deep Field (BDF) has enough ionizing power to form two large ionized bubbles that...
Is the Core-cusp Problem a Matter of Perspective? Jeans Anisotropic Modeling against Numerical Simulations
Mock member stars for 28 dwarf galaxies are constructed from the cosmological AURIGA simulation, which reflects the dynamical status of realistic stellar...
Is the initial mass function of low surface brightness galaxies dominated by low-mass stars?
The rotation curves of low surface brightness (LSB) galaxies suggest that they possess significantly higher mass-to-light (M/L) ratios than their high surface...
Is the orbit of the exoplanet WASP-43b really decaying? TESS and MuSCAT2 observations confirm no detection
Up to now, WASP-12b is the only hot Jupiter confirmed to have a decaying orbit. The case of WASP-43b is still under debate. Recent studies preferred or ruled...
Is the Solar Core Rotating Faster of Slower Than the Envelope?
The Sun is not a rigid body and it is well known that its surface rotation is differential, the polar regions rotating substantially slower than the equator...
Is the X-Ray Spectrum of the Seyfert 2 Galaxy NGC 5252 Intrinsically Flat?
The first X-ray observation of the Seyfert 2 galaxy NGC 5252 is reported. ASCA Astro-D collected approximately 4000 photons per detector, enough to perform an...
Is there Na I in the atmosphere of HD 209458b?. Effect of the centre-to-limb variation and Rossiter-McLaughlin effect in transmission spectroscopy studies
HD 209458b was the first transiting planet discovered, and the first for which an atmosphere, in particular Na I, was detected. With time, it has become one of...
ISOCAM observations in the Lockman Hole. I. The 14.3 μm shallow survey: Data reduction, catalogue, and optical identifications
We present the image and catalogue of the 14.3 μ shallow survey of 0.55 square degrees in the region of the Lockman Hole (10^h52^m03^s +57°21'46'', J2000) with...
ISOPHOT covers the largest wavelength range on ISO from 2.5 to 240μm. Its scientific capabilities include multi-filter and multi-aperture photometry...
