GMRT helps detect first merger in a nearby galaxy hosting Fast Radio Burst

A group of astronomers from Pune has obtained the first ever evidence of a galaxy merger that hosted a Fast Radio Burst (FRB) using the Giant Metrewave Radio Telescope (GMRT).

FRBs are extremely bright radio pulses that flicker for less than a few milliseconds from all directions in the sky, making them extremely difficult to detect. Astronomers around the world are uncertain about the source of FRBs. To this end, gaseous material and stars from nearby galaxies with FRBs are currently being studied.

Nearly 1,000 FRBs have been discovered since their first discovery about 15 years ago. Some FRBs that appear from a distance can be single flashes or have a well-defined periodicity, called repeater FRBs.

Researchers from TIFR – the National Center for Radio Astrophysics (NCRA), Pune and the University of California have selected a relatively nearby galaxy to house the FRB identified as FRB20180916B. It fires radio pulses every 16 days and is located on the outskirts of a galaxy about 5 billion light-years away. FRB20180916B was tracked by the Canadian Hydrogen Intensity Mapping Experiment (CHIME), which detected nearly 800 FRBs.

The researchers examined the 21-centimeter atomic hydrogen readout line acquired by the GMRT at 1420 MHz to map the distribution of gas in the FRB’s host galaxy.
While optical images of this galaxy didn’t reveal much interesting information, larger revelations came from subsequent radio imaging and mapping of the host galaxy’s atomic hydrogen gas.

Patterns of behaviour that emerge after trauma

Patterns of behaviour that emerge after trauma

Trauma is a deeply distressing or disturbing experience that can leave a lasting impact on a person’s mental and emotional health. It can result from a range of events, such as natural disasters, accidents, physical or emotional abuse, or military combat. Trauma can have a significant effect on a person’s behavior and can manifest in various ways. Here are some patterns of behavior that often emerge after trauma:

  1. Hyperarousal: After experiencing trauma, a person may feel constantly on edge, with heightened levels of anxiety and tension. This can manifest as irritability, restlessness, and difficulty sleeping.
  2. Avoidance: Trauma can also cause a person to avoid situations, people, or places that remind them of the traumatic experience. This can lead to social withdrawal, isolation, and a loss of interest in previously enjoyable activities.
  3. Emotional numbness: Trauma can cause a person to feel emotionally disconnected or numb, making it difficult for them to experience positive emotions such as joy or love.
  4. Hypervigilance: A person who has experienced trauma may be hyper-aware of their surroundings and perceive threats where none exist. This can lead to an increased sense of danger, which can trigger anxiety or panic attacks.
  5. Flashbacks: Trauma can cause a person to experience vivid and intrusive memories of the traumatic event. These flashbacks can be triggered by a range of stimuli, such as sights, sounds, or smells.
  6. Guilt and shame: Trauma can cause a person to experience feelings of guilt, shame, and self-blame. They may feel responsible for what happened to them, even when it was beyond their control.
  7. Substance abuse: Trauma can lead to the use of drugs or alcohol as a way of coping with difficult emotions. This can quickly become a self-destructive pattern of behavior that exacerbates the trauma.

It’s important to note that not everyone who experiences trauma will display all of these behaviors, and that each person’s response to trauma is unique. However, recognizing these patterns of behavior can help individuals and their loved ones identify when trauma may be a contributing factor to mental and emotional health challenges. Seeking professional support, such as therapy or counseling, can help individuals process their trauma and learn healthy coping mechanisms to manage their behavior.
