AbstractThe photometric and fundamental plane for a sample of early type galaxies(elliptical and lenticular galaxies) which belongs to Virgo cluster have been calculated by fitting the Sersic model ( r1/n-model) to the s...

In this paper we present preliminary results from the measurement and analysis of imag es of the ecliptic zoneobtained with MegaCam at Canada-France-Hawaii Telescope (CFHT) located a t Mauna Kea(Hawaii ). We areevaluat...

These studies were designed to elucidate the role of NPY in modulating the responses of mPFC to acute stress in mice. Fiberoptic photometry recorded a robust increase in the NPY fluorescent signal in the mPFC during expl...

In its first 2 yr of operation, the James Webb Space Telescope has enabled the discovery of a surprising number of UV-bright galaxies at z  ∼ 10–14. Their number density is still relatively uncertain, due to cosmic...

Synodic rotation periods and amplitudes are reported for 318 Magdalena, 455 Bruchsalia, 486 Cremona, 503 Evelyn, and 664 Judith. Fil: Colazo, Milagros Rita. Universidad Nacional de Córdoba. Facultad de Matemática, Astr...

Abstract Background Postoperative sleep disturbances are common and have been shown to exacerbate incisional pain by enhancing the central nervous system’s excitability. However, the specific neural circuit mechanisms ...

Abstract Fear and pain are two frequently co-occurring states that mammals need to orchestrate to ensure survival. Nevertheless, how the brain dynamically prioritizes between them remains poorly understood. Here, we demo...

Context. Co-orbital objects, also known as Trojans, are celestial bodies that share a 1:1 mean motion resonance orbit with a planet. Many planets in our Solar System hold Trojans, yet none has been confirmed in exoplanet...

Supernova (SN) iPTF13bvn in NGC 5806 was the first Type Ib SN to have been tentatively associated with a progenitor in pre-explosion images. We performed deep ultraviolet (UV) and optical Hubble Space Telescope observati...

Context. Globular clusters (GCs) are witnesses of the past accretion events onto the Milky Way. In particular, the GCs of the Sagittarius (Sgr) dwarf galaxy are important probes of an on-going merger. Aims. Our main goal...

Photometric CCD UB VI C photometry obtained for 4860 stars surrounding the embedded southern cluster SAI 113 (Skiff 8) is used to examine the reddening in the field and derive the distance to the cluster and nearby van G...

Abstract Background The insular cortex (IC), a pivotal hub for pain signal integration, projects extensively to the thalamus. However, the functional role of its specific projection to the central medial thalamic nucleus...

The evolution of starspots of the giant primaries of RS CVn systems is typically detected indirectly with photometric and spectroscopic monitoring. These observations suggest slowly-evolving stellar surfaces and can cons...

The emission-line object HDE 327083 has long been considered to be one of the most luminous stars in the Milky Way. Nevertheless, no reliable physical parameters have been published for it. Our high-resolution optical sp...

Small near-Earth asteroids (NEAs), diameters < 150 m, represent the most numerous yet one of the least well-understood populations among near-Earth objects, despite their potential hazard. Their rapid fading after discov...

We present the first public data release of the GOGREEN (Gemini Observations of Galaxies in Rich Early Environments) and GCLASS (Gemini CLuster Astrophysics Spectroscopic Survey) surveys of galaxies in dense environments...

Galaxies are often modeled as composites of separable components with distinct spectral signatures, implying that different wavelength ranges are only weakly correlated. They are not. We present a data-driven model that ...

We present the first public data release of the DDO51 band from the Stellar Abundances and Galactic Evolution Survey (SAGES), based on Nanshan One-meter Wide-field Telescope observations obtained between 2023 September a...

Abstract Background Chronic neuropathic pain is frequently accompanied by anxiety and depression, yet the cortical circuit mechanisms underlying this comorbidity remain unclear. The medial orbitofrontal cortex (mOFC) is ...

Context. The star V426 Sge (HBHA 1704-05), originally classified as an emission-line object and a semi-regular variable, brightened at the beginning of August 2018, showing signatures of a symbiotic star outburst. Aims. ...

Planetary nebulae (PNe) are pivotal for advancing our knowledge of stellar evolution and galactic chemical enrichment. Recentprogress in surveys and data analysis has revolutionized PN research, leading to the discovery ...

Context. The ESO public survey VISTA variables in the Vía Láctea (VVV) started in 2010. VVV targets 562 sq. deg in the Galactic bulge and an adjacent plane region and is expected to run for about five years. Aims. We ...
