A three-dimensional map of the hot Local Bubble using diffuse interstellar bands

School
ASTRONOMY

The Solar System is located within a low-density cavity, known as the Local Bubble, which appears to be filled with an X-ray emitting gas at a temperature of 10^6 K. Such conditions are too harsh for typical interstellar atoms and molecules to survive. There exists an enigmatic tracer of interstellar gas, known as Diffuse Interstellar Bands (DIB), which often appears as absorption features in stellar spectra. The carriers of these bands remain largely unidentified. Here we report the three-dimensional structure of the Local Bubble using two different DIB tracers (5780A and 5797A), which reveals that DIB carriers are present within the Bubble. ...

Investigation of Gold Nano-Particle Effects in Brachytherapy by an Electron Emitter Ophthalmic Plaque

Abstract:

During decades, all improvements and developments in radiation therapy technologies have been focused on its main goal: maximize the dose in the tumor and minimize it in surrounding normal tissues. Recently, scientists have some approachesto nanoparticles,especially Gold-Nano particles(GNPs), for dose localization. Here, the effect of GNPs in combination with electron brachytherapy in a model of eye tumor will be presented. Monte Carlo simulation was utilized and a complete anatomicalmodel of the ...

New Probes for Axion-like Particles at Hadron Colliders

School
PARTICLES AND ACCELERATORS

Abstract: Axion-like particles (ALPs) appear from spontaneous global symmetry breaking in many extensions of the Standard Model (SM). In this talk, I will show our bounds on ALP (a) model parameters at the LHC from the ALP production associated with a photon and a jet as well as single top and top quark pairs in a model-independent approach. In particular, I will explain that the ALP production associated with a photon plus a jet at the LHC is a promising channel with significant sensitivity to probe the ALP couplings to gluons and electroweak gauge bosons. The prospects are presented at the High Luminosity LHC including a realistic detector ...
