Spatial extension is an important characteristic for correctly associating gamma-ray-emitting sources with their counterparts at other wavelengths and obtaining unbiased model of spectra. We present a new method quantifying the spatial detected by Large Area Telescope (LAT), primary science instrument on Fermi Gamma-ray Space (Fermi). perform series Monte Carlo simulations to validate this tool calculate LAT threshold detecting sources. then test all in second Fermi-LAT catalog (2FGL)...
The first results from observations of the high-mass X-ray binary LS 5039 using Fermi Gamma-ray Space Telescope data between 2008 August and 2009 June are presented. Our indicate variability that is consistent with period, emission being modulated a period 3.903 ± 0.005 days; detection this modulation at GeV energies. light curve characterized by broad peak around superior conjunction in agreement inverse Compton scattering models. spectrum represented power law an exponential cutoff,...
Massive black holes at the centers of galaxies can launch powerful wide-angle winds that, if sustained over time, unbind gas from stellar bulges galaxies. These may be responsible for observed scaling relation between masses central and velocity dispersion stars in galactic bulges. Propagating through galaxy, wind should interact with interstellar medium creating a strong shock, similar to those supernovae explosions, which is able accelerate charged particles high energies. In this work we...
Context. Large and publicly available astronomical archives open up new possibilities to search for study Solar System objects. However, advanced techniques are required deal with the large amounts of data. These unbiased surveys can be used constrain size distribution minor bodies, which represents a piece puzzle formation models System. Aims. We aim identify asteroids in archival images from ESA Hubble Space Telescope (HST) Science data archive using mining. Methods. developed citizen...

It is already well known that hypermethylation of the O6-methylguanine DNA methyltransferase (MGMT) gene promoter a predictive biomarker response to temozolomide treatment and favorable outcomes in terms overall survival (OS) progression-free (PFS) glioblastoma (GBM) patients. Nevertheless, MGMT methylation status has not currently been introduced into routine clinical practice, as choice ideal technique tissue sample specimen still controversial. The aim this study was compare 2 analytical...
Abstract Background Immunoglobulin M multiple myeloma and Waldenström macroglobulinemia are two different hematological diseases with the common finding of an immunoglobulin monoclonal gammopathy unknown significance. However, clinical characteristics entities can overlap. Case presentation In this report, we describe cases neoplasm same histological bone marrow but behavior, cytogenetics, biological assessment. On basis comprehensive diagnostic workup, these patients were considered to have...
Axion-like particles (ALPs) are pseudo-Nambu-Goldstone bosons that emerge in various theories beyond the standard model. These can interact with high-energy photons external magnetic fields, influencing observed gamma-ray spectrum. This study analyzes 41.3 hrs of observational data from Perseus Galaxy Cluster collected MAGIC telescopes. We focused on spectra radio galaxy center cluster: NGC 1275. By modeling field surrounding this target, we searched for spectral indications ALP presence....
In patients with diabetes, impaired activity of ADAMTS13 (a disintegrin and metalloprotease thrombospondin type 1 repeats, member 13), the plasma that cleaves highly thrombogenic von Willebrand factor multimers, is a major risk cardiovascular events. Here, using Adamts13−/− mice made diabetic by streptozotocin, we investigated impact lack on development diabetes-associated end-organ complications. experienced shorter life span than their wild-type littermates. It was surprising animal death...
We report multiwavelength observations of the gravitationally lensed blazar QSO B0218+357 in 2016-2020. Optical, X-ray and GeV flares were detected. The contemporaneous MAGIC do not show significant very-high-energy (VHE, >= 100 GeV) gamma-ray emission. lack enhancement radio emission measured by OVRO indicates multi-zone nature from this object. constrain VHE duty cycle source to be < 16 2014-like per year (95% confidence). For first time for source, a broadband low-state SED is constructed...
The discovery of vast subsurface oceans hidden under kilometers ices on icy moons in our Solar System has sparked worldwide interests ascertaining their potential habitability. In the case Saturn&#8217;s moon Enceladus, supersonic plumes water vapour and grains have been observed by Cassini mission spewing from surface, giving us indirect knowledge composition this ocean. exact mechanisms however, effect ejected matter yet to be clearly understood. focus study is experimentally...
Supersonic plumes of water vapour and icy particles have been observed by the Cassini spacecraft during several flybys over Enceladus. These originate from Tiger Stripes located in South Polar Terrain (SPT), indicate presence a subsurface ocean under crust which is salty contains complex organic molecules. Other characteristics plumes, such as vent temperature, mass flow rate, velocity fraction can be used to determine conditions channel, linking surface. In this paper, we developed fluid...
Aims: $\gamma$ rays can be used as a tracer in the search of sources Galactic cosmic (CRs). We present deep observations Centre (GC) region with MAGIC telescopes, which we use for inferring underlying CR distribution. Methods: observed GC ${\approx}100$ hours telescopes from 2012 to 2017, at high zenith angles (58-70~deg). This implies larger energy threshold, but also an increased effective collection area compared low observations. Using new software, derive instrument response and...

The Lorentz Invariance Violation (LIV), a proposed consequence of certain quantum gravity (QG) scenarios, could instigate an energy-dependent group velocity for ultra-relativistic particles. This energy dependence, although suppressed by the massive QG scale $E_\mathrm{QG}$, expected to be on level Planck $1.22 \times 10^{19}$ GeV, is potentially detectable in astrophysical observations. In this scenario, cosmological distances traversed photons act as amplifier effect. By leveraging...
The Schwarzschild-Couder Telescope (SCT) is a candidate technology for medium-sized telescope within the Cherenkov Array, next generation ground based observatory very high energy gamma ray astronomy. SCT uses novel two-mirror design and expected to yield improvements in field of view image resolution compared traditional telescopes on single-mirror-dish optics.
